  3. WinRAR - What's new in the latest version
  6. Version 5.00 beta 1
  8. 1. New RAR 5.0 archiving format. You can use "RAR 5.0" option
  9. in archiving dialog or -ma command line switch to create
  10. RAR 5.0 archives.
  12. Older software including older WinRAR versions is not able to
  13. decompress RAR 5.0 archives, so if you plan to send an archive
  14. to other people, it is necessary to take the compatibility issue
  15. into consideration. You can select "RAR" instead of "RAR5" option
  16. in archiving dialog to create RAR 4.x archives compatible with
  17. previous WinRAR versions.
  19. 2. Changes in RAR 5.0 compression algorithm:
  21. a) maximum compression dictionary size is increased up to 1 GB
  22. in 64 bit WinRAR. 32 bit WinRAR version can use up to 256 MB
  23. dictionary when creating an archive. Both 32 bit and 64 bit
  24. versions can unpack archives with any dictionary size,
  25. including 1 GB;
  27. b) default dictionary size for RAR 5.0 is 32 MB, typically resulting
  28. in higher compression ratio and lower speed than RAR 4.x 4 MB.
  29. You can use "Dictionary size" archiving dialog option or -md<size>
  30. switch to change this value;
  32. c) -md<size> switch syntax is modified to support larger dictionary
  33. sizes. Append 'k', 'm' and 'g' modifiers to specify the size
  34. in kilo-, mega- and gigabytes, like -md64m for 64 MB dictionary.
  35. If modifiers are not present, megabytes are assumed,
  36. so -md64m is equal to -md64;
  38. d) RAR 5.0 format includes Intel IA-32 executable and delta
  39. compression algorithms, but RAR 4.x text, audio, true color
  40. and Itanium algorithms are not supported. These excluded algorithms
  41. are not efficient for modern data types and hardware configurations;
  43. e) RAR 5.0 decompression can utilize several CPU cores.
  44. Though not to same extent as in compression algorithm,
  45. it improves the decompression speed on large files
  46. with poorly compressible data or when using BLAKE2 checksums.
  48. 3. Changes in RAR 5.0 archive format:
  50. a) file times are stored as Coordinated Universal Time (UTC)
  51. instead of former local time, making file exchange among
  52. several time zones more straightforward;
  54. b) file names and archive comments use UTF-8 encoding.
  56. 4. RAR 5.0 recovery record is based on Reed-Solomon error correction
  57. codes. If recovery record size is large enough, 5% and more,
  58. the new error correction scheme provides much higher resistance to
  59. multiple damages comparing to RAR 4.x recovery record.
  60. Smaller record, such as 1 - 2%, or less random damage type would
  61. result in less difference between 4.x and 5.0. For single continuous
  62. damage 4.x and 5.0 efficiency is about the same.
  64. Additionally to usual data erasures, the new recovery record
  65. is able to detect deletions and insertions of much larger size
  66. than in previous RAR versions. Maximum insertion size is several
  67. megabytes. Maximum deletion size depends on the damage type
  68. and in some cases can be as large as the recovery record size.
  70. Still, the best recovery performance and efficiency is achieved
  71. if no deletions and insertions are present, so all data including
  72. damaged sectors preserve their original positions. Thus, if you use
  73. some special software to copy an archive from damaged media,
  74. it is better to choose the mode, when damaged sectors are filled by
  75. zeroes or any other data instead of cutting them out completely
  76. from resulting file.
  78. RAR 5.0 recovery record is more resistant to damage of recovery record
  79. itself and can utilize a partially corrupt recovery record data.
  80. Note, though, that "Repair" command does not fix broken blocks
  81. in recovery record. Only file data are corrected. After successful
  82. archive repair, you may need to create a new recovery record
  83. for saved files.
  85. New recovery record is not based on 512 byte sectors anymore
  86. and incorporates more complicated data structures. So it is impossible
  87. to specify its size in sectors. For RAR 5.0 archives the parameter of
  88. -rr[N] switch and rr[N] command is always treated as a percent of
  89. archive size regardless of presence of % character. Typically N%
  90. recovery record can repair up to N% of continuously damaged data
  91. and increases the archive size by only slightly more than N%.
  92. Ability to fix multiple damages is proportional to N.
  94. We used "Screaming Fast Galois Field Arithmetic Using Intel
  95. SIMD Instructions" paper by James S. Plank, Kevin M. Greenan
  96. and Ethan L. Miller to improve Reed-Solomon coding performance.
  97. Also we are grateful to Artem Drobanov and Bulat Ziganshin
  98. for samples and ideas allowed to make Reed-Solomon coding
  99. more efficient.
  101. 5. "Test" command verifies validity of RAR 5.0 recovery record.
  102. Recovery record is tested after processing all archived files.
  104. If corrupt archive contains the recovery record, it might be possible
  105. to repair it even if recovery record validity test is failed.
  106. "Repair" command attempts to utilize even a partially damaged
  107. recovery record. So treat the negative recovery record test result
  108. as a reason to re-create the archive if original files are still
  109. available, but not as a reason to avoid "Repair" command.
  111. 6. Changes in RAR 5.0 encryption algorithm:
  113. a) encryption algorithm is changed from AES-128 to AES-256 in CBC mode.
  114. Key derivation function is based on PBKDF2 using HMAC-SHA256;
  116. b) special password verification value allows to detect most of
  117. wrong passwords without necessity to unpack the entire file;
  119. c) if archive headers are not encrypted ("Encrypt file names" option
  120. is off), file checksums for encrypted RAR 5.0 files are modified
  121. using a special password dependent algorithm, to make impossible
  122. guessing file contents based on checksums. Do not expect such
  123. encrypted file checksums to match usual CRC32 and BLAKE2 values.
  125. 7. RAR 5.0 archives allow to utilize 256 bit length BLAKE2sp hash
  126. ( ) instead of 32 bit CRC32 as a file checksum.
  127. Enable "Use BLAKE2 file checksum" option in "Options" page of
  128. archiving dialog or specify -htb command line switch to use BLAKE2
  129. checksums.
  131. While producing slightly larger archives, BLAKE2 can be used
  132. for file contents identification. If two files have the same
  133. BLAKE2 value, it practically guarantees that file contents
  134. is the same. BLAKE2 error detection property is also stronger
  135. than in much shorter CRC32.
  137. 8. Features removed:
  139. a) authenticity verification feature did not provide the required
  140. level of reliability and was removed;
  142. b) switch -en (do not add "end of archive" block) is not supported
  143. by RAR 5.0 archives, which always have the end of archive block.
  144. This block helps WinRAR to safely skip external data like
  145. digital signatures appended to archive;
  147. c) old style extension based arcname.rNN volume names are not
  148. supported by RAR 5.0 archives, which use only arcname.partN.rar
  149. volume names;
  151. d) file comments are not supported anymore both in RAR 4.x
  152. and RAR 5.0 archives. Console RAR 'cf' command is removed.
  153. It does not affect the archive comment support, which is present
  154. in both versions of archive format and is not planned for removal.
  156. 9. "Set password" command and "Dictionary size" option are moved to
  157. "General" page of archiving dialog.
  159. 10. You can use "Save symbolic links as links" option on "Advanced" page
  160. of archiving dialog to save and restore NTFS symbolic links
  161. and reparse points as links, so their contents is not archived.
  162. Command line equivalent of this option is -ol switch.
  164. Similar option for NTFS hard links is "Save hard links as links".
  165. Its command line equivalent is -oh switch.
  167. Both options are available only for RAR 5.0 archive format.
  169. 11. Added extraction only support for XZ archive format.
  171. 12. Changes in recovery volume processing in RAR 5.0 archive format:
  173. a) maximum number of RAR+REV volumes in RAR 5.0 format is 65535
  174. instead of 255;
  176. b) recovery volume operations are faster than in RAR 4.x;
  178. c) additionally to recovery data, RAR 5.0 REV files also store
  179. service information such as checksums of protected RAR files.
  180. So they are slightly larger than RAR volumes which they protect.
  181. If you plan to copy individual RAR and REV files to some removable
  182. media, you need to take it into account and specify RAR volume
  183. size by a few kilobytes smaller than media size.
  185. 13. Maximum path length for files in RAR and ZIP archives is increased
  186. up to 2048 characters.
  188. 14. Command line RAR returns the exit code 11 if it can detect that
  189. user entered a wrong password. This code can be returned only
  190. for RAR 5.0 archives. It is impossible to distinguish a wrong
  191. password and data damage for RAR 4.x archives.
  193. 15. 'v' and 'l' commands display archived file names in the end of line,
  194. not in that beginning as before. Also some fields previously
  195. available in 'l' and 'v' output are now shown only by 'lt' and 'vt'.
  197. 'vt' and 'lt' commands provide the detailed multiline information
  198. for every archived file.
  200. 'vta' and 'lta' also include service headers into list.
  202. 16. Now the default charset for filelists in commands like
  203. 'rar a arcname @filelist' is ANSI for both WinRAR and console RAR.
  204. In previous versions it was ANSI for WinRAR and OEM for console RAR.
  205. You can use -sc<charset>l switch to override this default.
  207. 17. Internal WinRAR viewer can detect and display files in UTF-8
  208. and UTF-16 little endian encodings.
  210. 18. UTF-16 little endian encoding is used in RAR and WinRAR log file
  211. rar.log, so Unicode file names are stored in the log correctly.
  212. WinRAR automatically truncates the old rar.log file in non-Unicode
  213. format to avoid mixing different encoding in the same log file.
  214. In case of console RAR you need to delete the old rar.log manually,
  215. otherwide RAR will append UTF-16 messages to existing rar.log.
  217. 19. Command line 'r' (repair) command can include an optional destpath\
  218. parameter defining the destination folder for repaired archive:
  220. rar r archive.rar destpath\
  223. Version 4.20
  225. 1. Changes in RAR compression:
  227. a) RAR general compression algorithm is optimized for better
  228. utilization of several processor cores. While some speed gain
  229. is possible even in single processor mode, best results
  230. are achieved in multi-core environment.
  232. Speed gain depends on data type and average file size.
  233. Several cores are utilized more efficiently when compressing
  234. large files.
  236. b) we had to increase memory requirements to achieve higher
  237. compression speed. General RAR compression algorithm allocates
  238. about 120 MB comparing to 40 MB in WinRAR 4.11;
  240. c) RAR text compression algorithm cannot utilize several CPU cores
  241. efficiently, so its performance in multiprocessor environment
  242. is much lower than for general algorithm. Also its decompression
  243. speed is much lower than in general algorithm regardless of
  244. CPU number. So we decided to disable the text algorithm by default.
  246. If you need maximum possible compression ratio for plain text data
  247. regardless of speed, you can enable the text compression
  248. in "Advanced compression parameter" dialog. Press "Compression..."
  249. button on "Advanced" page of archiving dialog to access it.
  250. You can also change this option permanently in default compression
  251. profile;
  253. In the command line mode the text compression can be enabled
  254. with -mct switch;
  256. d) "Fastest" (-m1) compression mode also supports several processor
  257. cores now. In 4.11 it could use only a single processor core.
  259. 2. RAR general decompression algorithm speed is slightly improved,
  260. though not to same extent as RAR compression. RAR decompression
  261. is not able to use several processor cores, so its performance
  262. does not depend on a number of cores.
  264. 3. Changes in ZIP compression:
  266. a) now ZIP compression supports several processor cores resulting
  267. in noticeably higher performance in multi-core environment.
  268. Single CPU ZIP compression is also faster than in 4.11;
  270. b) memory use for ZIP compression is increased to about 15 MB.
  272. 4. Recovery volume creating and processing can use several CPU cores
  273. resulting in higher speed. Though, typically hard drive seek speed
  274. is a limiting factor for recovery volumes, so this gain is most
  275. noticeable when working with solid state drive.
  277. 5. Now the allowed <threads> value for -mt<threads> switch is 1 - 32,
  278. not 0 - 16 as before.
  280. 6. "Find files" command can search data in 7-Zip archives.
  281. Previously "Find files" did not support .7z archive format.
  283. 7. Windows 2000 is not supported by WinRAR and WinRAR self-extracting
  284. modules anymore.
  286. 8. "Save current settings" button in "Advanced SFX options" dialog
  287. is now available only when converting an existing archive to SFX.
  288. Options saved with this button are applied only to convert to SFX
  289. operation.
  291. If you create or update SFX archive, only SFX options stored
  292. in default compression profile are used. Options saved
  293. in "Advanced SFX options" dialog are ignored for these operations.
  296. Version 4.11
  298. 1. Bugs fixed:
  300. a) WinRAR did not store NTFS "Compressed" attribute, when creating
  301. RAR archives;
  303. b) WinRAR crashed in command line mode if @filelist parameter
  304. was present and 'filelist' did not exist. This bug affected
  305. only WinRAR.exe, not RAR.exe;
  307. c) if -x*\somefolder\* exclusion mask was specified when archiving
  308. and if name of current folder contained 'somefolder',
  309. WinRAR excluded all files and stopped creating an archive;
  311. d) GUI self-extracting archives did not work in Windows
  312. Preinstallation Environment (Windows PE).
  315. Version 4.10
  317. 1. WinRAR can create ZIP archives of practically any size.
  319. 2 GB archive size and 65535 file number ZIP limitations of previous
  320. WinRAR versions are not valid anymore.
  322. 2. WinRAR can create multivolume ZIP archives, which are also known as
  323. split ZIP files.
  325. ZIP volumes have names like '', 'volname.z01', 'volname.z02'.
  326. Use a volume with ".zip" file extension in all archive processing
  327. operations like starting extraction or opening an archive.
  329. Unlike RAR volumes, ZIP volumes cannot be self-extracting.
  331. WinRAR needs to have access to all ZIP volumes of multivolume file set
  332. at the same time, when creating or unpacking them. So it is impossible
  333. to create or unpack ZIP volumes on removable disks, one volume
  334. per disk. You need to create them all in the same folder.
  336. 3. Added the high precision file time support in ZIP archives.
  337. WinRAR can store and extract modification, creation and last access
  338. file time in ZIP archives with 100 nanosecond precision.
  340. You need to set "High precision modification time" option in "Time"
  341. part of archiving dialog to store all 3 times in archive.
  342. Set appropriate "File time" options in "Advanced" part of extraction
  343. dialog to choose times to extract.
  345. 4. Added support for Unicode names stored in ZIP extra field data.
  346. Different ZIP tools store Unicode names either in file header
  347. or in ZIP extra field and now WinRAR can correctly process both types
  348. of Unicode names.
  350. 5. "Synchronize archive contents" option and -as command line switch are
  351. supported in ZIP format.
  353. 6. Modifications of switch -ag behavior:
  355. a) -ag can be used with all RAR and WinRAR commands, not just
  356. with archiving only;
  358. b) 'N' format character behavior differs in archiving and non-archiving
  359. operations. When archiving, it is incremented until the first unused
  360. name is found. In non-archiving operations like extracting it selects
  361. the existing archive preceding the first unused name;
  363. c) 'I' format character allows to specify minutes regardless of presence
  364. and position of 'H' (hours) in format string. It can be used
  365. instead of 'M' (minutes), when you wish to place minutes before hours
  366. or do not need hours at all.
  368. 7. By default, WinRAR proposes to update an archive if viewer modified
  369. an opened file or created any new files. New "Ignore modifications for"
  370. option in "Settings/Viewer" dialog allows to disable such behavior.
  371. You can enter one or several file masks separated by spaces here
  372. and WinRAR will not prompt to update an archive if file created
  373. or modified by viewer matches one of these masks.
  375. 8. Changes in volume size input field. Now you can select size units
  376. in the drop down list to the right of volume size. Previous way
  377. to define size modifiers, by entering 'k', 'm', etc. character
  378. after the numeric size value, is also supported.
  380. 9. Changes in "Predefined sizes" in "Define volume sizes" dialog.
  381. Floppies and ZIP disks are replaced by 5 MB and 100 MB volumes,
  382. added new entries for maximum FAT32 file size and for Blu-ray disks.
  384. 10. New "Wipe files if password is set" option in "Options" page of
  385. archiving dialog. If you prefer to always delete encrypted files
  386. securely, you can enable "Wipe files if password is set"
  387. in the default compression profile.
  389. 11. New "Wipe temporary files/Encrypted only" option in "Settings/Security".
  390. It allows to use a slower and more secure delete for temporary files
  391. extracted from archives identified by WinRAR as encrypted.
  392. Quick delete is used for all other temporary files.
  394. 12. Changes in "Convert archives" command:
  396. a) now it is possible to convert encrypted archives. Previously
  397. "Convert archives" command skipped them.
  399. Though, if you still prefer to skip them, you can do it
  400. by enabling "Skip encrypted archives" option in "Convert archives"
  401. dialog. It might be useful if you wish to run the conversion
  402. command in unattended mode, avoiding password prompts;
  404. b) special "rar2" archive type, which was specific for RAR 1.x
  405. and 2.x archives, is removed. Now "rar" archive type controls
  406. conversion of all versions of RAR archives.
  408. Since the convert command does not need to detect RAR archive
  409. version anymore, the initial search for archives is performed
  410. faster, resulting in shorter delay before displaying
  411. "Convert archives" dialog.
  413. 13. New -log[fmt][=name] switch allows to write archive and file names
  414. to log file in archiving command for RAR and ZIP formats and also
  415. in extracting, deleting and listing commands for RAR format.
  417. This switch is especially useful, when you need to further process
  418. an archive created with -ag or -v switches, because -log provides
  419. the archive name generated by WinRAR.
  421. 14. New -@[+] switch allows to process all parameters starting from
  422. '@' character either as file names (-@) or as file lists (-@+).
  424. 15. "Setup program" SFX options are moved from "General" to "Setup" page
  425. of "Advanced SFX options" dialog. Both "Run after extraction"
  426. and "Run before extraction" are now multiline, so it is possible
  427. to specify several setup programs for same SFX archive.
  429. 16. "SetupCode" SFX script command instructs SFX archive to wait
  430. for termination of setup program and return the exit code of
  431. setup program increased by 1000 as the exit code of SFX executable.
  433. GUI equivalent of this command is "Wait and return exit code" option
  434. on "Setup" page of "Advanced SFX options" dialog.
  436. 17. SFX does not support "S" (create in the top level of Start Menu)
  437. "Shortcut" command mode anymore. Recent Windows versions do not allow
  438. programs to add items to the top of Start Menu.
  440. 18. Volume size in archiving and wizard dialogs can be specified as
  441. a decimal fraction. Decimal mark is defined by Windows regional
  442. settings.
  444. -v<size> command line switch also allows decimal fractions.
  445. In command line mode the dot (.) is always used as the decimal mark.
  446. For example, -v1.5g switch means 1.5 gigabytes.
  449. Version 4.01
  451. 1. Added support for file sizes stored in binary format in TAR archives.
  452. Some TAR archives use the binary size format instead of octal
  453. for files larger than 8 GB.
  455. 2. Bugs fixed:
  457. a) "Repair" command failed to properly reconstruct structure
  458. of RAR archives, which contained at least one file with packed
  459. size exceeding 4 GB.
  461. This bug did not affect the recovery record based repair.
  462. It happened only if recovery record was not found and WinRAR
  463. performed reconstruction of archive structure;
  465. b) even if "Do not extract paths" option in "Advanced" part of
  466. extraction dialog was set as the default, WinRAR still unpacked
  467. file paths if called from Explorer context menu;
  469. c) after entering a wrong password for encrypted ZIP archive,
  470. sometimes WinRAR ignored subsequent attempts to enter a valid
  471. password;
  473. d) "Wizard" command did not allow to create self-extracting
  474. and multivolume archives, when compressing a single folder
  475. or a file without extension;
  477. e) "Import settings from file" command did not restore multiline
  478. comments in WinRAR compression profiles;
  480. f) when converting RAR volumes having name1.name2.part#.rar name format,
  481. "Convert archives" command erroneously removed ".name2" name part.
  482. So resulting archive had name1.rar file name instead of expected
  483. name1.name2.rar;
  485. g) RAR could crash when creating a new archive with -agNNN switch
  486. if archive number in generated name was 110 or larger;
  488. h) WinRAR failed to display non-English file names in 7-Zip archives
  489. properly if they used a non-default code page. It was the display
  490. only problem, such names were unpacked correctly.
  493. Version 4.00
  495. 1. RAR decompression speed is improved. Depending on data type,
  496. decompression can be up to 30% faster than in previous versions.
  498. Both the general RAR algorithm and most of special RAR multimedia
  499. methods benefit from this improvement. The only module of RAR
  500. algorithm, which is not affected, is "Text compression" method.
  502. 2. Changes in ISO support:
  504. a) UDF support is upgraded to UDF 2.50 revision. It makes possible
  505. to unpack most of Blu-ray ISO files;
  507. b) when browsing UDF ISO file, UDF revision number is displayed
  508. after the "UDF" format name in WinRAR address bar
  509. and in archive information dialog;
  511. c) WinRAR sets the folder modification date when unpacking folders
  512. stored in UDF and ISO9660 files.
  514. 3. Changes in password dialog:
  516. a) WinRAR uses the same format of password dialog both when archiving
  517. and extracting, so "Show password" option is available also
  518. when extracting;
  520. b) "Organize passwords..." button in password dialog provides
  521. access to password organizer interface, where you can specify
  522. your frequently used passwords. You will be able to access these
  523. saved passwords using the drop down list or autocomplete feature
  524. in password dialog.
  526. It is important to know that saved passwords are not encrypted
  527. and anybody having access to your computer can view them.
  528. Use "Organize passwords" feature only if your computer is
  529. protected from unauthorized access;
  531. c) "Use for all archives" option is available in password dialog
  532. when unpacking several archives at once. You can utilize it
  533. to apply an entered password to all archives.
  535. If you use this option with an empty password, WinRAR will skip
  536. all encrypted archives;
  538. d) Unlike previous versions, the password from default compression
  539. profile is not used for extraction.
  541. If you wish to use the same password for all extracting archives,
  542. press "Organize passwords..." button in the password dialog
  543. and define a new password entry, specifying "*" file mask
  544. in "Select for archives" field.
  546. 4. In Windows 7 WinRAR will display the total operation progress
  547. also on WinRAR icon on Windows taskbar. You can disable it using
  548. "Taskbar progress bar" option on "General" page of WinRAR settings.
  550. 5. Numerous Unicode support improvements allow to process non-English
  551. file names more smoothly. These improvements include:
  553. a) better Unicode handling in WinRAR in "Rename", "Convert",
  554. "Find" and other commands, in folder tree panel, in password
  555. request dialog and in many other parts of WinRAR interface;
  557. b) correctly displayed Unicode names in WinRAR items in Explorer
  558. context menus;
  560. c) Unicode support in .lng files, making WinRAR localization
  561. possible for Unicode only languages.
  563. 6. Changes in -x<file> switch syntax. Now you can specify a wildcard
  564. exclusion mask for folders. Such mask must have the trailing '\'
  565. character, like -x*tmp*\ or -x*\temp\
  567. 7. New "Extract relative paths" option in "Advanced" part of extraction
  568. dialog. If you browse some archive subfolder in WinRAR shell
  569. and enable "Extract relative paths" option, the path part up to
  570. and including the current subfolder will be removed from extracted
  571. file paths.
  573. For example, if you are inside of "Backup\MyData" archive folder
  574. and extract "Images" folder, it will be extracted as "Images",
  575. not as "Backup\MyData\Images".
  577. This option is the new default extraction mode, but you can change
  578. the default back to WinRAR 3.x style. Just select "Extract full paths"
  579. and then press "Save settings" in "General" part of extraction dialog.
  581. 8. Windows 98, Windows Me and Windows NT are not supported by WinRAR
  582. and WinRAR self-extracting modules anymore. Minimum Windows version
  583. required for WinRAR 4.0 is Windows 2000.
  585. If you need to run WinRAR on older Windows, you can download
  586. previous WinRAR versions from
  588. 9. If TAR, TAR.GZ or TAR.BZ2 archive contains symbolic or hard links
  589. and if destination file system is NTFS, WinRAR will create these
  590. links when unpacking such archive. WinRAR will create symbolic links
  591. as symbolic and hard links as hard in Windows Vista and newer
  592. and it will create all links as hard in older Windows.
  594. If destination file system is FAT32 or any other not supporting
  595. file links, WinRAR will skip links when unpacking TAR, TAR.GZ
  596. and TAR.BZ2 archives.
  598. 10. Recovery volume processing involves less disk seek operations
  599. resulting in higher performance.
  601. 11. You can select Windows 7 library in tree panel in extraction dialog
  602. and WinRAR will use its default save location as the destination path.
  604. 12. "Report" command allows to select HTML, Unicode text and usual text
  605. as output format for report file. Unlike previous WinRAR versions,
  606. now WinRAR preservers Unicode characters in reports when using HTML
  607. or Unicode text format. So non-English characters in file names
  608. will be displayed properly in such reports.
  610. 13. Message list in GUI SFX archives displays only operation status
  611. and error messages. It does not contain names of all extracted files
  612. anymore. This change improves the speed and reduces memory requirements
  613. for SFX archives containing a large number of files. Also it makes
  614. easier to locate error messages, because they are not hidden among
  615. extracted file names.
  617. 14. GUI SFX archives display "Extract" button instead of "Install"
  618. if no "Setup" or "Presetup" commands are present in the archive
  619. comment. If you prefer "Install" button, but do not need to
  620. execute any setup programs, you can add "Setup=<>" command.
  622. 15. WinRAR displays the current percent above the operation progress bar
  623. when repairing an archive containing the recovery record
  624. and when processing recovery volumes.
  626. 16. WinRAR limits the maximum possible volume size to 4 GB minus 1 byte
  627. when creating RAR volumes on a disk with FAT or FAT32 file system
  628. in volume size autodetecting mode. These file systems do not support
  629. 4 GB and larger files.
  631. 17. If "Wait if other WinRAR copies are active" option is enabled
  632. and WinRAR waits for another copy, you can press "Continue" button
  633. in command progress window to force WinRAR to stop waiting.
  634. So now "Continue" button allows to override the state of
  635. "Wait if other WinRAR copies are active" option for current operation.
  637. 18. WinRAR displays one password request instead of two, when saving
  638. an encrypted file back to RAR or ZIP archive after modifying it
  639. in some external editor. Previous WinRAR versions usually requested
  640. the password twice, both when extracting the original file
  641. and archiving its modified copy. Only RAR archives with encrypted
  642. file names were processed with the single password prompt.
  644. 19. New error code 10 ("no files") is added to list of error codes
  645. returned in command line mode by RAR and WinRAR. This new code
  646. can be returned by archive, extract, delete and repair commands.
  647. It means that RAR did not find any files matched the specified
  648. file or archive mask.
  650. 20. File name area in file overwrite dialog occupies several lines now.
  651. It makes possible to display much longer names.
  653. 21. Now switch -ep3 converts not only disk letters, but also UNC paths.
  654. So \\server\share will be converted to __server\share when archiving
  655. and restored to the original \\server\share when extracting with -ep3.
  657. 22. New "Background extraction" option in "Advanced" part of extraction
  658. dialog places WinRAR into background, when extracting files.
  659. You can save its default state with "Save settings" button in "General"
  660. part of extraction dialog, just like for other extraction options.
  662. "Background archiving" option from the default compression profile
  663. does not affect the extraction behavior anymore.
  665. 23. "Mode..." button in operation progress window is enabled also
  666. when extracting or testing archives. It provides access to
  667. "Command parameters" dialog, where you can set "Turn PC off when done"
  668. option for extraction and test operations.
  670. Previously this dialog was accessible only when archiving.
  672. 24. Bugs fixed:
  674. a) renaming a file in archive could also rename all other files
  675. with the same name in other folders of the same archive;
  677. b) previous versions displayed the wrong total packed size
  678. in "Info" command for multivolume CAB archives;
  680. c) in ZIP archives 'U' (update) and 'F' (fresh) commands could
  681. erroneously update even files not specified in the command line.
  682. It happened only for files in current folder which names matched
  683. files in ZIP archive. This bug was not present in usual 'A' (add)
  684. archiving mode.
  687. Version 3.93
  689. 1. Bugs fixed:
  691. a) in WinRAR 3.92 -xd:\path\folder switch could also exclude folders,
  692. which path does not match the path specified in the switch
  693. and only the folder name is the same as specified;
  695. b) switches -y -or did not work correctly together. Switch -or was
  696. ignored in presence of -y.
  699. Version 3.92
  701. 1. If you start WinRAR command from Explorer context menu in multiple
  702. monitor configuration, the command dialog will be displayed
  703. on the same monitor as context menu. In previous versions it was
  704. always displayed on primary monitor.
  706. 2. WinRAR "Compress and email..." context menu command adds the archive
  707. name to email subject. Previous versions left the subject blank.
  709. 3. In RAR 3.91 -x<mask> switch could also exclude folders from archiving
  710. even if mask contained wilcard characters and did not contain a path.
  711. For example, -x*. excluded all those folders, which do not have
  712. the extension in the name. Now -x switch uses RAR 3.80 approach
  713. for masks without path, excluding folders only if mask does not
  714. contain wildcards and matches the folder name exactly.
  716. 4. Bugs fixed:
  718. a) WinRAR 3.91 reported the incorrect "Unexpected end of archive"
  719. error, when opening an empty ZIP archive created with
  720. "New WinRAR ZIP archive" context menu command;
  722. b) if "Delete archive" option was enabled when unpacking several
  723. ZIP archives and if one of archives was damaged, WinRAR did not
  724. delete archives after the damaged one, even if they were unpacked
  725. successfully;
  727. c) if file matched two different masks in RarFiles.lst, WinRAR
  728. could select the last match. Normally, if neither of masks
  729. is a subset of another, the first match must be chosen.
  732. Version 3.91
  734. 1. This version can decompress 7-Zip archives created with
  735. LZMA2 algorithm.
  737. 2. Now a password is requested only once when unpacking 7z archives
  738. with encrypted file names from context menu. WinRAR 3.90 asked it
  739. twice.
  741. 3. This version can unpack tar.bz2 archives consisting of several
  742. smaller bz2 streams merged together. Previous versions unpacked
  743. only the first nested bz2 stream in such composite archive.
  745. 4. WinRAR displays CRC32 of files inside of usual .gz (not .tar.gz)
  746. archives. Previous versions left this field blank for GZIP files.
  748. 5. Bugs fixed:
  750. a) WinRAR 3.90 displayed "Save" button instead of "Open" or "OK"
  751. in "Find archive" dialog ("Open archive" command in "File" menu
  752. and "Browse..." command in archiving dialog);
  754. b) WinRAR could display incorrect file names when browsing malformed
  755. ZIP archives;
  757. c) WinRAR 3.90 failed to decompress LZH archives created with
  758. "-lh7-" algorithm;
  760. d) WinRAR 3.90 could fail to delete a part of files after archiving
  761. if delete to Recycle Bin was enabled. This bug was present
  762. when working in Windows XP, but not in Windows Vista and Windows 7;
  764. e) when unpacking ISO file using WinRAR "Extract files..." command
  765. in Explorer context menu, WinRAR could unpack same archived files
  766. twice during the same operation. It displayed the overwrite prompt
  767. when unpacking files for the second time;
  769. f) hexadecimal search in WinRAR 3.90 "Find" command and console RAR
  770. "ih" command failed to find matches if first byte in search string
  771. was greater than 127.
  774. Version 3.90
  776. 1. WinRAR version for Windows x64 is available. If you use
  777. Windows x64, it is strongly recommended to install 64 bit
  778. WinRAR version. It provides a higher performance and better
  779. shell integration than 32 bit version.
  781. 2. RAR compression speed is improved for multi-core
  782. and multi-CPU systems. This improvement is most noticeable
  783. in Windows Vista and Windows 7 operating systems.
  785. 3. "Remove duplicate folders from extraction path" option
  786. in "Settings/Compression" dialog is replaced by more universal
  787. "Remove redundant folders from extraction path" option.
  788. This option will eliminate redundant archive name based folders
  789. from extraction path if you unpack an archive with
  790. "Extract to DestName\" context menu command and if archive
  791. root folder contains only one folder and no files.
  793. 4. Changes in "Extraction path and options" dialog:
  795. a) "New folder" button creates a new subfolder in currently
  796. selected folder;
  798. b) F2 key renames a selected folder in the folders tree;
  800. c) F5 key updated the tree pane contents;
  802. d) Del key removes a selected folder in the folders tree.
  804. 5. You can enable "Show seconds" option in "Settings/File list"
  805. dialog if you wish to see seconds in file dates in file list
  806. in WinRAR shell.
  808. 6. "Where to check for SFX archives" options group
  809. in "Settings/Integration/Context menus items" dialog lets
  810. you to control processing of SFX archives in context menus.
  811. For example, if you frequently right click ".exe" files
  812. on slow network disks, you can turn off "Network disks" options
  813. to minimize the delay before displaying the context menu.
  815. 7. If you sort files by name in the file list in WinRAR shell,
  816. WinRAR will use the new logical file name sorting,
  817. same as in Windows Explorer, considering digits in file names
  818. by their numerical value. So files will be sorted as
  819. 1.txt, 2.txt, 10.txt instead of previous 1.txt, 10.txt, 2.txt.
  820. This new sort behavior is available in Windows XP Service Pack 2
  821. and newer.
  823. 8. Ctrl+W key combination can be used to close the main WinRAR window
  824. also as WinRAR viewer windows. "View as Windows text" shortcut
  825. in WinRAR viewer changed from Ctrl+W to Ctrl+I.
  827. 9. New command line switch -r- disables recursion completely.
  828. So 'rar a -r- arc dirname' command will add only the empty
  829. dirname folder and ignore its contents. By default, if dirname
  830. does not include wildcards, RAR adds its contents even if
  831. -r switch is not specified.
  833. 10. If used when extracting, the new command line switch -ai forces
  834. RAR to ignore file attributes. When using this switch,
  835. extracted files will always have attributes assigned by
  836. operating system to a newly created file by default.
  838. 11. If output file name is not specified in "cw" command, console RAR
  839. will send comment data to stdout.
  841. 12. When compressing stdin data with -si[name] switch, RAR sets
  842. modification time of archived entry to current system time.
  843. Previous RAR versions did not fill this field, resulting in
  844. meaningless modification time for stdin.
  846. 13. Message displayed when you place the mouse cursor on WinRAR
  847. tray icon includes the archive name now. Previously only
  848. time left and total percent were displayed for archiving operations.
  850. 14. New 'Shutdown' variable in 'Software\WinRAR\Policy' registry key
  851. allows to disable "Turn PC off when done" option for security reasons.
  852. Read "Configuration settings/Registry variables" for more details.
  854. 15. Better shell extension performance. Now WinRAR context menu will be
  855. more responsive when working with thousands of selected files.
  857. 16. Improved compatibility with high DPI Windows display mode.
  859. 17. Bugs fixed:
  861. a) WinRAR could fail to open tar or tar.gz archive if such archive
  862. contained a file larger than 8 GB;
  864. b) WinRAR context menu did not work properly in Windows 7 beta
  865. if icons in context menus were enabled and user clicked
  866. a file inside of Windows 7 Library folder;
  868. c) previous WinRAR versions failed to rename files having 5 or more
  869. continuous spaces in the name. WinRAR shell does not display
  870. such spaces for safety reasons, because they can hide an actual
  871. file extension. But this security measure prevented the rename
  872. command to work properly.
