- WinRAR - What's new in the latest version
- Version 5.00 beta 1
- 1. New RAR 5.0 archiving format. You can use "RAR 5.0" option
- in archiving dialog or -ma command line switch to create
- RAR 5.0 archives.
- Older software including older WinRAR versions is not able to
- decompress RAR 5.0 archives, so if you plan to send an archive
- to other people, it is necessary to take the compatibility issue
- into consideration. You can select "RAR" instead of "RAR5" option
- in archiving dialog to create RAR 4.x archives compatible with
- previous WinRAR versions.
- 2. Changes in RAR 5.0 compression algorithm:
- a) maximum compression dictionary size is increased up to 1 GB
- in 64 bit WinRAR. 32 bit WinRAR version can use up to 256 MB
- dictionary when creating an archive. Both 32 bit and 64 bit
- versions can unpack archives with any dictionary size,
- including 1 GB;
- b) default dictionary size for RAR 5.0 is 32 MB, typically resulting
- in higher compression ratio and lower speed than RAR 4.x 4 MB.
- You can use "Dictionary size" archiving dialog option or -md<size>
- switch to change this value;
- c) -md<size> switch syntax is modified to support larger dictionary
- sizes. Append 'k', 'm' and 'g' modifiers to specify the size
- in kilo-, mega- and gigabytes, like -md64m for 64 MB dictionary.
- If modifiers are not present, megabytes are assumed,
- so -md64m is equal to -md64;
- d) RAR 5.0 format includes Intel IA-32 executable and delta
- compression algorithms, but RAR 4.x text, audio, true color
- and Itanium algorithms are not supported. These excluded algorithms
- are not efficient for modern data types and hardware configurations;
- e) RAR 5.0 decompression can utilize several CPU cores.
- Though not to same extent as in compression algorithm,
- it improves the decompression speed on large files
- with poorly compressible data or when using BLAKE2 checksums.
- 3. Changes in RAR 5.0 archive format:
- a) file times are stored as Coordinated Universal Time (UTC)
- instead of former local time, making file exchange among
- several time zones more straightforward;
- b) file names and archive comments use UTF-8 encoding.
- 4. RAR 5.0 recovery record is based on Reed-Solomon error correction
- codes. If recovery record size is large enough, 5% and more,
- the new error correction scheme provides much higher resistance to
- multiple damages comparing to RAR 4.x recovery record.
- Smaller record, such as 1 - 2%, or less random damage type would
- result in less difference between 4.x and 5.0. For single continuous
- damage 4.x and 5.0 efficiency is about the same.
- Additionally to usual data erasures, the new recovery record
- is able to detect deletions and insertions of much larger size
- than in previous RAR versions. Maximum insertion size is several
- megabytes. Maximum deletion size depends on the damage type
- and in some cases can be as large as the recovery record size.
- Still, the best recovery performance and efficiency is achieved
- if no deletions and insertions are present, so all data including
- damaged sectors preserve their original positions. Thus, if you use
- some special software to copy an archive from damaged media,
- it is better to choose the mode, when damaged sectors are filled by
- zeroes or any other data instead of cutting them out completely
- from resulting file.
- RAR 5.0 recovery record is more resistant to damage of recovery record
- itself and can utilize a partially corrupt recovery record data.
- Note, though, that "Repair" command does not fix broken blocks
- in recovery record. Only file data are corrected. After successful
- archive repair, you may need to create a new recovery record
- for saved files.
- New recovery record is not based on 512 byte sectors anymore
- and incorporates more complicated data structures. So it is impossible
- to specify its size in sectors. For RAR 5.0 archives the parameter of
- -rr[N] switch and rr[N] command is always treated as a percent of
- archive size regardless of presence of % character. Typically N%
- recovery record can repair up to N% of continuously damaged data
- and increases the archive size by only slightly more than N%.
- Ability to fix multiple damages is proportional to N.
- We used "Screaming Fast Galois Field Arithmetic Using Intel
- SIMD Instructions" paper by James S. Plank, Kevin M. Greenan
- and Ethan L. Miller to improve Reed-Solomon coding performance.
- Also we are grateful to Artem Drobanov and Bulat Ziganshin
- for samples and ideas allowed to make Reed-Solomon coding
- more efficient.
- 5. "Test" command verifies validity of RAR 5.0 recovery record.
- Recovery record is tested after processing all archived files.
- If corrupt archive contains the recovery record, it might be possible
- to repair it even if recovery record validity test is failed.
- "Repair" command attempts to utilize even a partially damaged
- recovery record. So treat the negative recovery record test result
- as a reason to re-create the archive if original files are still
- available, but not as a reason to avoid "Repair" command.
- 6. Changes in RAR 5.0 encryption algorithm:
- a) encryption algorithm is changed from AES-128 to AES-256 in CBC mode.
- Key derivation function is based on PBKDF2 using HMAC-SHA256;
- b) special password verification value allows to detect most of
- wrong passwords without necessity to unpack the entire file;
- c) if archive headers are not encrypted ("Encrypt file names" option
- is off), file checksums for encrypted RAR 5.0 files are modified
- using a special password dependent algorithm, to make impossible
- guessing file contents based on checksums. Do not expect such
- encrypted file checksums to match usual CRC32 and BLAKE2 values.
- 7. RAR 5.0 archives allow to utilize 256 bit length BLAKE2sp hash
- ( https://blake2.net ) instead of 32 bit CRC32 as a file checksum.
- Enable "Use BLAKE2 file checksum" option in "Options" page of
- archiving dialog or specify -htb command line switch to use BLAKE2
- checksums.
- While producing slightly larger archives, BLAKE2 can be used
- for file contents identification. If two files have the same
- BLAKE2 value, it practically guarantees that file contents
- is the same. BLAKE2 error detection property is also stronger
- than in much shorter CRC32.
- 8. Features removed:
- a) authenticity verification feature did not provide the required
- level of reliability and was removed;
- b) switch -en (do not add "end of archive" block) is not supported
- by RAR 5.0 archives, which always have the end of archive block.
- This block helps WinRAR to safely skip external data like
- digital signatures appended to archive;
- c) old style extension based arcname.rNN volume names are not
- supported by RAR 5.0 archives, which use only arcname.partN.rar
- volume names;
- d) file comments are not supported anymore both in RAR 4.x
- and RAR 5.0 archives. Console RAR 'cf' command is removed.
- It does not affect the archive comment support, which is present
- in both versions of archive format and is not planned for removal.
- 9. "Set password" command and "Dictionary size" option are moved to
- "General" page of archiving dialog.
- 10. You can use "Save symbolic links as links" option on "Advanced" page
- of archiving dialog to save and restore NTFS symbolic links
- and reparse points as links, so their contents is not archived.
- Command line equivalent of this option is -ol switch.
- Similar option for NTFS hard links is "Save hard links as links".
- Its command line equivalent is -oh switch.
- Both options are available only for RAR 5.0 archive format.
- 11. Added extraction only support for XZ archive format.
- 12. Changes in recovery volume processing in RAR 5.0 archive format:
- a) maximum number of RAR+REV volumes in RAR 5.0 format is 65535
- instead of 255;
- b) recovery volume operations are faster than in RAR 4.x;
- c) additionally to recovery data, RAR 5.0 REV files also store
- service information such as checksums of protected RAR files.
- So they are slightly larger than RAR volumes which they protect.
- If you plan to copy individual RAR and REV files to some removable
- media, you need to take it into account and specify RAR volume
- size by a few kilobytes smaller than media size.
- 13. Maximum path length for files in RAR and ZIP archives is increased
- up to 2048 characters.
- 14. Command line RAR returns the exit code 11 if it can detect that
- user entered a wrong password. This code can be returned only
- for RAR 5.0 archives. It is impossible to distinguish a wrong
- password and data damage for RAR 4.x archives.
- 15. 'v' and 'l' commands display archived file names in the end of line,
- not in that beginning as before. Also some fields previously
- available in 'l' and 'v' output are now shown only by 'lt' and 'vt'.
- 'vt' and 'lt' commands provide the detailed multiline information
- for every archived file.
- 'vta' and 'lta' also include service headers into list.
- 16. Now the default charset for filelists in commands like
- 'rar a arcname @filelist' is ANSI for both WinRAR and console RAR.
- In previous versions it was ANSI for WinRAR and OEM for console RAR.
- You can use -sc<charset>l switch to override this default.
- 17. Internal WinRAR viewer can detect and display files in UTF-8
- and UTF-16 little endian encodings.
- 18. UTF-16 little endian encoding is used in RAR and WinRAR log file
- rar.log, so Unicode file names are stored in the log correctly.
- WinRAR automatically truncates the old rar.log file in non-Unicode
- format to avoid mixing different encoding in the same log file.
- In case of console RAR you need to delete the old rar.log manually,
- otherwide RAR will append UTF-16 messages to existing rar.log.
- 19. Command line 'r' (repair) command can include an optional destpath\
- parameter defining the destination folder for repaired archive:
- rar r archive.rar destpath\
- Version 4.20
- 1. Changes in RAR compression:
- a) RAR general compression algorithm is optimized for better
- utilization of several processor cores. While some speed gain
- is possible even in single processor mode, best results
- are achieved in multi-core environment.
- Speed gain depends on data type and average file size.
- Several cores are utilized more efficiently when compressing
- large files.
- b) we had to increase memory requirements to achieve higher
- compression speed. General RAR compression algorithm allocates
- about 120 MB comparing to 40 MB in WinRAR 4.11;
- c) RAR text compression algorithm cannot utilize several CPU cores
- efficiently, so its performance in multiprocessor environment
- is much lower than for general algorithm. Also its decompression
- speed is much lower than in general algorithm regardless of
- CPU number. So we decided to disable the text algorithm by default.
- If you need maximum possible compression ratio for plain text data
- regardless of speed, you can enable the text compression
- in "Advanced compression parameter" dialog. Press "Compression..."
- button on "Advanced" page of archiving dialog to access it.
- You can also change this option permanently in default compression
- profile;
- In the command line mode the text compression can be enabled
- with -mct switch;
- d) "Fastest" (-m1) compression mode also supports several processor
- cores now. In 4.11 it could use only a single processor core.
- 2. RAR general decompression algorithm speed is slightly improved,
- though not to same extent as RAR compression. RAR decompression
- is not able to use several processor cores, so its performance
- does not depend on a number of cores.
- 3. Changes in ZIP compression:
- a) now ZIP compression supports several processor cores resulting
- in noticeably higher performance in multi-core environment.
- Single CPU ZIP compression is also faster than in 4.11;
- b) memory use for ZIP compression is increased to about 15 MB.
- 4. Recovery volume creating and processing can use several CPU cores
- resulting in higher speed. Though, typically hard drive seek speed
- is a limiting factor for recovery volumes, so this gain is most
- noticeable when working with solid state drive.
- 5. Now the allowed <threads> value for -mt<threads> switch is 1 - 32,
- not 0 - 16 as before.
- 6. "Find files" command can search data in 7-Zip archives.
- Previously "Find files" did not support .7z archive format.
- 7. Windows 2000 is not supported by WinRAR and WinRAR self-extracting
- modules anymore.
- 8. "Save current settings" button in "Advanced SFX options" dialog
- is now available only when converting an existing archive to SFX.
- Options saved with this button are applied only to convert to SFX
- operation.
- If you create or update SFX archive, only SFX options stored
- in default compression profile are used. Options saved
- in "Advanced SFX options" dialog are ignored for these operations.
- Version 4.11
- 1. Bugs fixed:
- a) WinRAR did not store NTFS "Compressed" attribute, when creating
- RAR archives;
- b) WinRAR crashed in command line mode if @filelist parameter
- was present and 'filelist' did not exist. This bug affected
- only WinRAR.exe, not RAR.exe;
- c) if -x*\somefolder\* exclusion mask was specified when archiving
- and if name of current folder contained 'somefolder',
- WinRAR excluded all files and stopped creating an archive;
- d) GUI self-extracting archives did not work in Windows
- Preinstallation Environment (Windows PE).
- Version 4.10
- 1. WinRAR can create ZIP archives of practically any size.
- 2 GB archive size and 65535 file number ZIP limitations of previous
- WinRAR versions are not valid anymore.
- 2. WinRAR can create multivolume ZIP archives, which are also known as
- split ZIP files.
- ZIP volumes have names like 'volname.zip', 'volname.z01', 'volname.z02'.
- Use a volume with ".zip" file extension in all archive processing
- operations like starting extraction or opening an archive.
- Unlike RAR volumes, ZIP volumes cannot be self-extracting.
- WinRAR needs to have access to all ZIP volumes of multivolume file set
- at the same time, when creating or unpacking them. So it is impossible
- to create or unpack ZIP volumes on removable disks, one volume
- per disk. You need to create them all in the same folder.
- 3. Added the high precision file time support in ZIP archives.
- WinRAR can store and extract modification, creation and last access
- file time in ZIP archives with 100 nanosecond precision.
- You need to set "High precision modification time" option in "Time"
- part of archiving dialog to store all 3 times in archive.
- Set appropriate "File time" options in "Advanced" part of extraction
- dialog to choose times to extract.
- 4. Added support for Unicode names stored in ZIP extra field data.
- Different ZIP tools store Unicode names either in file header
- or in ZIP extra field and now WinRAR can correctly process both types
- of Unicode names.
- 5. "Synchronize archive contents" option and -as command line switch are
- supported in ZIP format.
- 6. Modifications of switch -ag behavior:
- a) -ag can be used with all RAR and WinRAR commands, not just
- with archiving only;
- b) 'N' format character behavior differs in archiving and non-archiving
- operations. When archiving, it is incremented until the first unused
- name is found. In non-archiving operations like extracting it selects
- the existing archive preceding the first unused name;
- c) 'I' format character allows to specify minutes regardless of presence
- and position of 'H' (hours) in format string. It can be used
- instead of 'M' (minutes), when you wish to place minutes before hours
- or do not need hours at all.
- 7. By default, WinRAR proposes to update an archive if viewer modified
- an opened file or created any new files. New "Ignore modifications for"
- option in "Settings/Viewer" dialog allows to disable such behavior.
- You can enter one or several file masks separated by spaces here
- and WinRAR will not prompt to update an archive if file created
- or modified by viewer matches one of these masks.
- 8. Changes in volume size input field. Now you can select size units
- in the drop down list to the right of volume size. Previous way
- to define size modifiers, by entering 'k', 'm', etc. character
- after the numeric size value, is also supported.
- 9. Changes in "Predefined sizes" in "Define volume sizes" dialog.
- Floppies and ZIP disks are replaced by 5 MB and 100 MB volumes,
- added new entries for maximum FAT32 file size and for Blu-ray disks.
- 10. New "Wipe files if password is set" option in "Options" page of
- archiving dialog. If you prefer to always delete encrypted files
- securely, you can enable "Wipe files if password is set"
- in the default compression profile.
- 11. New "Wipe temporary files/Encrypted only" option in "Settings/Security".
- It allows to use a slower and more secure delete for temporary files
- extracted from archives identified by WinRAR as encrypted.
- Quick delete is used for all other temporary files.
- 12. Changes in "Convert archives" command:
- a) now it is possible to convert encrypted archives. Previously
- "Convert archives" command skipped them.
- Though, if you still prefer to skip them, you can do it
- by enabling "Skip encrypted archives" option in "Convert archives"
- dialog. It might be useful if you wish to run the conversion
- command in unattended mode, avoiding password prompts;
- b) special "rar2" archive type, which was specific for RAR 1.x
- and 2.x archives, is removed. Now "rar" archive type controls
- conversion of all versions of RAR archives.
- Since the convert command does not need to detect RAR archive
- version anymore, the initial search for archives is performed
- faster, resulting in shorter delay before displaying
- "Convert archives" dialog.
- 13. New -log[fmt][=name] switch allows to write archive and file names
- to log file in archiving command for RAR and ZIP formats and also
- in extracting, deleting and listing commands for RAR format.
- This switch is especially useful, when you need to further process
- an archive created with -ag or -v switches, because -log provides
- the archive name generated by WinRAR.
- 14. New -@[+] switch allows to process all parameters starting from
- '@' character either as file names (-@) or as file lists (-@+).
- 15. "Setup program" SFX options are moved from "General" to "Setup" page
- of "Advanced SFX options" dialog. Both "Run after extraction"
- and "Run before extraction" are now multiline, so it is possible
- to specify several setup programs for same SFX archive.
- 16. "SetupCode" SFX script command instructs SFX archive to wait
- for termination of setup program and return the exit code of
- setup program increased by 1000 as the exit code of SFX executable.
- GUI equivalent of this command is "Wait and return exit code" option
- on "Setup" page of "Advanced SFX options" dialog.
- 17. SFX does not support "S" (create in the top level of Start Menu)
- "Shortcut" command mode anymore. Recent Windows versions do not allow
- programs to add items to the top of Start Menu.
- 18. Volume size in archiving and wizard dialogs can be specified as
- a decimal fraction. Decimal mark is defined by Windows regional
- settings.
- -v<size> command line switch also allows decimal fractions.
- In command line mode the dot (.) is always used as the decimal mark.
- For example, -v1.5g switch means 1.5 gigabytes.
- Version 4.01
- 1. Added support for file sizes stored in binary format in TAR archives.
- Some TAR archives use the binary size format instead of octal
- for files larger than 8 GB.
- 2. Bugs fixed:
- a) "Repair" command failed to properly reconstruct structure
- of RAR archives, which contained at least one file with packed
- size exceeding 4 GB.
- This bug did not affect the recovery record based repair.
- It happened only if recovery record was not found and WinRAR
- performed reconstruction of archive structure;
- b) even if "Do not extract paths" option in "Advanced" part of
- extraction dialog was set as the default, WinRAR still unpacked
- file paths if called from Explorer context menu;
- c) after entering a wrong password for encrypted ZIP archive,
- sometimes WinRAR ignored subsequent attempts to enter a valid
- password;
- d) "Wizard" command did not allow to create self-extracting
- and multivolume archives, when compressing a single folder
- or a file without extension;
- e) "Import settings from file" command did not restore multiline
- comments in WinRAR compression profiles;
- f) when converting RAR volumes having name1.name2.part#.rar name format,
- "Convert archives" command erroneously removed ".name2" name part.
- So resulting archive had name1.rar file name instead of expected
- name1.name2.rar;
- g) RAR could crash when creating a new archive with -agNNN switch
- if archive number in generated name was 110 or larger;
- h) WinRAR failed to display non-English file names in 7-Zip archives
- properly if they used a non-default code page. It was the display
- only problem, such names were unpacked correctly.
- Version 4.00
- 1. RAR decompression speed is improved. Depending on data type,
- decompression can be up to 30% faster than in previous versions.
- Both the general RAR algorithm and most of special RAR multimedia
- methods benefit from this improvement. The only module of RAR
- algorithm, which is not affected, is "Text compression" method.
- 2. Changes in ISO support:
- a) UDF support is upgraded to UDF 2.50 revision. It makes possible
- to unpack most of Blu-ray ISO files;
- b) when browsing UDF ISO file, UDF revision number is displayed
- after the "UDF" format name in WinRAR address bar
- and in archive information dialog;
- c) WinRAR sets the folder modification date when unpacking folders
- stored in UDF and ISO9660 files.
- 3. Changes in password dialog:
- a) WinRAR uses the same format of password dialog both when archiving
- and extracting, so "Show password" option is available also
- when extracting;
- b) "Organize passwords..." button in password dialog provides
- access to password organizer interface, where you can specify
- your frequently used passwords. You will be able to access these
- saved passwords using the drop down list or autocomplete feature
- in password dialog.
- It is important to know that saved passwords are not encrypted
- and anybody having access to your computer can view them.
- Use "Organize passwords" feature only if your computer is
- protected from unauthorized access;
- c) "Use for all archives" option is available in password dialog
- when unpacking several archives at once. You can utilize it
- to apply an entered password to all archives.
- If you use this option with an empty password, WinRAR will skip
- all encrypted archives;
- d) Unlike previous versions, the password from default compression
- profile is not used for extraction.
- If you wish to use the same password for all extracting archives,
- press "Organize passwords..." button in the password dialog
- and define a new password entry, specifying "*" file mask
- in "Select for archives" field.
- 4. In Windows 7 WinRAR will display the total operation progress
- also on WinRAR icon on Windows taskbar. You can disable it using
- "Taskbar progress bar" option on "General" page of WinRAR settings.
- 5. Numerous Unicode support improvements allow to process non-English
- file names more smoothly. These improvements include:
- a) better Unicode handling in WinRAR in "Rename", "Convert",
- "Find" and other commands, in folder tree panel, in password
- request dialog and in many other parts of WinRAR interface;
- b) correctly displayed Unicode names in WinRAR items in Explorer
- context menus;
- c) Unicode support in .lng files, making WinRAR localization
- possible for Unicode only languages.
- 6. Changes in -x<file> switch syntax. Now you can specify a wildcard
- exclusion mask for folders. Such mask must have the trailing '\'
- character, like -x*tmp*\ or -x*\temp\
- 7. New "Extract relative paths" option in "Advanced" part of extraction
- dialog. If you browse some archive subfolder in WinRAR shell
- and enable "Extract relative paths" option, the path part up to
- and including the current subfolder will be removed from extracted
- file paths.
- For example, if you are inside of "Backup\MyData" archive folder
- and extract "Images" folder, it will be extracted as "Images",
- not as "Backup\MyData\Images".
- This option is the new default extraction mode, but you can change
- the default back to WinRAR 3.x style. Just select "Extract full paths"
- and then press "Save settings" in "General" part of extraction dialog.
- 8. Windows 98, Windows Me and Windows NT are not supported by WinRAR
- and WinRAR self-extracting modules anymore. Minimum Windows version
- required for WinRAR 4.0 is Windows 2000.
- If you need to run WinRAR on older Windows, you can download
- previous WinRAR versions from ftp://ftp.rarlab.com/rar
- 9. If TAR, TAR.GZ or TAR.BZ2 archive contains symbolic or hard links
- and if destination file system is NTFS, WinRAR will create these
- links when unpacking such archive. WinRAR will create symbolic links
- as symbolic and hard links as hard in Windows Vista and newer
- and it will create all links as hard in older Windows.
- If destination file system is FAT32 or any other not supporting
- file links, WinRAR will skip links when unpacking TAR, TAR.GZ
- and TAR.BZ2 archives.
- 10. Recovery volume processing involves less disk seek operations
- resulting in higher performance.
- 11. You can select Windows 7 library in tree panel in extraction dialog
- and WinRAR will use its default save location as the destination path.
- 12. "Report" command allows to select HTML, Unicode text and usual text
- as output format for report file. Unlike previous WinRAR versions,
- now WinRAR preservers Unicode characters in reports when using HTML
- or Unicode text format. So non-English characters in file names
- will be displayed properly in such reports.
- 13. Message list in GUI SFX archives displays only operation status
- and error messages. It does not contain names of all extracted files
- anymore. This change improves the speed and reduces memory requirements
- for SFX archives containing a large number of files. Also it makes
- easier to locate error messages, because they are not hidden among
- extracted file names.
- 14. GUI SFX archives display "Extract" button instead of "Install"
- if no "Setup" or "Presetup" commands are present in the archive
- comment. If you prefer "Install" button, but do not need to
- execute any setup programs, you can add "Setup=<>" command.
- 15. WinRAR displays the current percent above the operation progress bar
- when repairing an archive containing the recovery record
- and when processing recovery volumes.
- 16. WinRAR limits the maximum possible volume size to 4 GB minus 1 byte
- when creating RAR volumes on a disk with FAT or FAT32 file system
- in volume size autodetecting mode. These file systems do not support
- 4 GB and larger files.
- 17. If "Wait if other WinRAR copies are active" option is enabled
- and WinRAR waits for another copy, you can press "Continue" button
- in command progress window to force WinRAR to stop waiting.
- So now "Continue" button allows to override the state of
- "Wait if other WinRAR copies are active" option for current operation.
- 18. WinRAR displays one password request instead of two, when saving
- an encrypted file back to RAR or ZIP archive after modifying it
- in some external editor. Previous WinRAR versions usually requested
- the password twice, both when extracting the original file
- and archiving its modified copy. Only RAR archives with encrypted
- file names were processed with the single password prompt.
- 19. New error code 10 ("no files") is added to list of error codes
- returned in command line mode by RAR and WinRAR. This new code
- can be returned by archive, extract, delete and repair commands.
- It means that RAR did not find any files matched the specified
- file or archive mask.
- 20. File name area in file overwrite dialog occupies several lines now.
- It makes possible to display much longer names.
- 21. Now switch -ep3 converts not only disk letters, but also UNC paths.
- So \\server\share will be converted to __server\share when archiving
- and restored to the original \\server\share when extracting with -ep3.
- 22. New "Background extraction" option in "Advanced" part of extraction
- dialog places WinRAR into background, when extracting files.
- You can save its default state with "Save settings" button in "General"
- part of extraction dialog, just like for other extraction options.
- "Background archiving" option from the default compression profile
- does not affect the extraction behavior anymore.
- 23. "Mode..." button in operation progress window is enabled also
- when extracting or testing archives. It provides access to
- "Command parameters" dialog, where you can set "Turn PC off when done"
- option for extraction and test operations.
- Previously this dialog was accessible only when archiving.
- 24. Bugs fixed:
- a) renaming a file in archive could also rename all other files
- with the same name in other folders of the same archive;
- b) previous versions displayed the wrong total packed size
- in "Info" command for multivolume CAB archives;
- c) in ZIP archives 'U' (update) and 'F' (fresh) commands could
- erroneously update even files not specified in the command line.
- It happened only for files in current folder which names matched
- files in ZIP archive. This bug was not present in usual 'A' (add)
- archiving mode.
- Version 3.93
- 1. Bugs fixed:
- a) in WinRAR 3.92 -xd:\path\folder switch could also exclude folders,
- which path does not match the path specified in the switch
- and only the folder name is the same as specified;
- b) switches -y -or did not work correctly together. Switch -or was
- ignored in presence of -y.
- Version 3.92
- 1. If you start WinRAR command from Explorer context menu in multiple
- monitor configuration, the command dialog will be displayed
- on the same monitor as context menu. In previous versions it was
- always displayed on primary monitor.
- 2. WinRAR "Compress and email..." context menu command adds the archive
- name to email subject. Previous versions left the subject blank.
- 3. In RAR 3.91 -x<mask> switch could also exclude folders from archiving
- even if mask contained wilcard characters and did not contain a path.
- For example, -x*. excluded all those folders, which do not have
- the extension in the name. Now -x switch uses RAR 3.80 approach
- for masks without path, excluding folders only if mask does not
- contain wildcards and matches the folder name exactly.
- 4. Bugs fixed:
- a) WinRAR 3.91 reported the incorrect "Unexpected end of archive"
- error, when opening an empty ZIP archive created with
- "New WinRAR ZIP archive" context menu command;
- b) if "Delete archive" option was enabled when unpacking several
- ZIP archives and if one of archives was damaged, WinRAR did not
- delete archives after the damaged one, even if they were unpacked
- successfully;
- c) if file matched two different masks in RarFiles.lst, WinRAR
- could select the last match. Normally, if neither of masks
- is a subset of another, the first match must be chosen.
- Version 3.91
- 1. This version can decompress 7-Zip archives created with
- LZMA2 algorithm.
- 2. Now a password is requested only once when unpacking 7z archives
- with encrypted file names from context menu. WinRAR 3.90 asked it
- twice.
- 3. This version can unpack tar.bz2 archives consisting of several
- smaller bz2 streams merged together. Previous versions unpacked
- only the first nested bz2 stream in such composite archive.
- 4. WinRAR displays CRC32 of files inside of usual .gz (not .tar.gz)
- archives. Previous versions left this field blank for GZIP files.
- 5. Bugs fixed:
- a) WinRAR 3.90 displayed "Save" button instead of "Open" or "OK"
- in "Find archive" dialog ("Open archive" command in "File" menu
- and "Browse..." command in archiving dialog);
- b) WinRAR could display incorrect file names when browsing malformed
- ZIP archives;
- c) WinRAR 3.90 failed to decompress LZH archives created with
- "-lh7-" algorithm;
- d) WinRAR 3.90 could fail to delete a part of files after archiving
- if delete to Recycle Bin was enabled. This bug was present
- when working in Windows XP, but not in Windows Vista and Windows 7;
- e) when unpacking ISO file using WinRAR "Extract files..." command
- in Explorer context menu, WinRAR could unpack same archived files
- twice during the same operation. It displayed the overwrite prompt
- when unpacking files for the second time;
- f) hexadecimal search in WinRAR 3.90 "Find" command and console RAR
- "ih" command failed to find matches if first byte in search string
- was greater than 127.
- Version 3.90
- 1. WinRAR version for Windows x64 is available. If you use
- Windows x64, it is strongly recommended to install 64 bit
- WinRAR version. It provides a higher performance and better
- shell integration than 32 bit version.
- 2. RAR compression speed is improved for multi-core
- and multi-CPU systems. This improvement is most noticeable
- in Windows Vista and Windows 7 operating systems.
- 3. "Remove duplicate folders from extraction path" option
- in "Settings/Compression" dialog is replaced by more universal
- "Remove redundant folders from extraction path" option.
- This option will eliminate redundant archive name based folders
- from extraction path if you unpack an archive with
- "Extract to DestName\" context menu command and if archive
- root folder contains only one folder and no files.
- 4. Changes in "Extraction path and options" dialog:
- a) "New folder" button creates a new subfolder in currently
- selected folder;
- b) F2 key renames a selected folder in the folders tree;
- c) F5 key updated the tree pane contents;
- d) Del key removes a selected folder in the folders tree.
- 5. You can enable "Show seconds" option in "Settings/File list"
- dialog if you wish to see seconds in file dates in file list
- in WinRAR shell.
- 6. "Where to check for SFX archives" options group
- in "Settings/Integration/Context menus items" dialog lets
- you to control processing of SFX archives in context menus.
- For example, if you frequently right click ".exe" files
- on slow network disks, you can turn off "Network disks" options
- to minimize the delay before displaying the context menu.
- 7. If you sort files by name in the file list in WinRAR shell,
- WinRAR will use the new logical file name sorting,
- same as in Windows Explorer, considering digits in file names
- by their numerical value. So files will be sorted as
- 1.txt, 2.txt, 10.txt instead of previous 1.txt, 10.txt, 2.txt.
- This new sort behavior is available in Windows XP Service Pack 2
- and newer.
- 8. Ctrl+W key combination can be used to close the main WinRAR window
- also as WinRAR viewer windows. "View as Windows text" shortcut
- in WinRAR viewer changed from Ctrl+W to Ctrl+I.
- 9. New command line switch -r- disables recursion completely.
- So 'rar a -r- arc dirname' command will add only the empty
- dirname folder and ignore its contents. By default, if dirname
- does not include wildcards, RAR adds its contents even if
- -r switch is not specified.
- 10. If used when extracting, the new command line switch -ai forces
- RAR to ignore file attributes. When using this switch,
- extracted files will always have attributes assigned by
- operating system to a newly created file by default.
- 11. If output file name is not specified in "cw" command, console RAR
- will send comment data to stdout.
- 12. When compressing stdin data with -si[name] switch, RAR sets
- modification time of archived entry to current system time.
- Previous RAR versions did not fill this field, resulting in
- meaningless modification time for stdin.
- 13. Message displayed when you place the mouse cursor on WinRAR
- tray icon includes the archive name now. Previously only
- time left and total percent were displayed for archiving operations.
- 14. New 'Shutdown' variable in 'Software\WinRAR\Policy' registry key
- allows to disable "Turn PC off when done" option for security reasons.
- Read "Configuration settings/Registry variables" for more details.
- 15. Better shell extension performance. Now WinRAR context menu will be
- more responsive when working with thousands of selected files.
- 16. Improved compatibility with high DPI Windows display mode.
- 17. Bugs fixed:
- a) WinRAR could fail to open tar or tar.gz archive if such archive
- contained a file larger than 8 GB;
- b) WinRAR context menu did not work properly in Windows 7 beta
- if icons in context menus were enabled and user clicked
- a file inside of Windows 7 Library folder;
- c) previous WinRAR versions failed to rename files having 5 or more
- continuous spaces in the name. WinRAR shell does not display
- such spaces for safety reasons, because they can hide an actual
- file extension. But this security measure prevented the rename
- command to work properly.
