  3. PATCHCLEAN.PS1
  4. =================
  5. Version 1.0 Patch Folder Cleaner by Greg Linares (@Laughing_Mantis)
  6.  
  7. This Tool will go through the patch folders created by PatchExtract.PS1 and look for files created older
  8. than 30 days prior to the current date and move these to a sub folder named "OLD" in the patch folders.
  9.  
  10. This will help identify higher priority binaries that were likely updated in the current patch cycle window.
  11.  
  12. =======    
  13. USAGE
  14. =======
  15. Powershell -ExecutionPolicy Bypass -File PatchClean.ps1 -Path C:\Patches\MS16-121\x86\
  16.  
  17. This would go through the x86 folder and create a subfolder named C:\Patches\MS16-121\x86\OLD\ and place
  18. older files and their folders in that directory.
  19.  
  20. Files remaining in C:\Patches\MS16-121\x86\ should be considered likely targets for containing patched binaries
  21.  
  22. Empty folders are automatically cleaned and removed at the end of processing.
  23.  
  24. -PATH <STRING:FolderPath> [REQUIRED] [NO DEFAULT]
  25.     Specified the folder that the script will parse and look for older files
