Ultima versione rilasciata dal team Rarlab. Molti bug corretti e diverse implementazioni. WinRAR e WinZip rappresentano il top dei programmi per la compressione di dati.

Version 3.20

• Previous WinRAR and RAR versions stored only the file modification
  time and only in DOS FAT format with 2 seconds precision.
  While it was enough for FAT, modern file systems provide a higher
  precision. Now RAR format can preserve modification, creation and
  last access time with the precision up to 0.0000001 second.
  The following changes had been done to support this facility:
  
  a) new "Time" part of archiving dialog includes "File time to store"
  options controlling file time processing. Other time related
  options also had been moved from "Backup" to "Time" section;
  
  b) new "Advanced" part of extraction dialog contains "File time"
  options allowing to select time fields to restore;
  
  c) command line -ts switch chooses time fields to process
  and precision of these fields;

Time precision provided by ZIP format is not changed and equal
to 2 seconds.

• Changes in the extraction dialog:
  
  a) extraction dialog has been split to "General" and "Advanced"
  parts;
  
  b) "Display files in Explorer" option in "General" part instructs
  WinRAR to open Explorer window and display contents of
  destination folder when extraction is done;
  
  c) "Save settings" button saves the current state of both parts
  ("General" and "Advanced"). Saved state will be used as
  the default when activating the dialog next time. WinRAR saves
  all options except the destination path;
  
  d) "Advanced" part includes "File time" options allowing to
  select time fields to restore;
  
  e) new "Set file security" option in "Advanced" part controls
  restoring of NTFS file security information. Previous versions
  always extracted this information.
  
• It is possible to rename files inside of RAR archives.
  It can be done either with "Rename file" command in "Commands"
  menu or in the context menu displaying on the right mouse click.
  In the command line mode you may use 'rn' command for this
  purpose.
  
• "Next volume" dialog allows to choose the disk or folder for
  a new volume. WinRAR displays this dialog when creating volumes
  on removable disks or if "Pause after each volume" option
  is switched on. Previous versions did not allow to modify
  the volume name here.
  
• "Test" and "Convert" commands can be applied to archives
  directly from Explorer context menu. By default these menu
  items are disabled, but you may enable them in WinRAR
  "Settings/Integration/Context menu items..." dialog.
  
• "Pause" item added to context menu displayed on the right mouse
  button click on WinRAR tray icon. So you may pause WinRAR minimized
  to tray and continue it without restoring WinRAR to normal window.
  
• If one of SFX volumes is missing, SFX archive displays
  "Next volume" dialog proposing to browse for required volume.
  
• WinRAR allows to resize the window containing results of "Find"
  command. It saves modified window dimensions and restores them
  when using "Find" next time.
  
• Toolbar:
  
  a) "Toolbars..." button in "Settings/General" activates the dialog
  allowing to turn on or off the main WinRAR toolbar, the additional
  small toolbar containing "Up one level" button and the address bar
  with path or archive information;
  
  b)buttons may have a variable width. So few large button titles
  in localized versions will not increase the total toolbar size
  too much like it happened before;
  
  c) if the width of buttons exceeds the width of toolbar,
  you may click on the small arrow at the right side of toolbar
  and choose hidden buttons from the menu.
  
• Console RAR 'lb' and 'vb' commands list contents of archive
  in the bare mode - file names without any additional information.
  
• WinRAR recognizes one more tar long file name extension
  designed to overcome 100 characters file name limit in tar archives.
  
• Gzip archives contained zero in the file time field are processed
  correctly. Previous versions could display random date values
  for such archives.
  
• Recovery volumes:
  
  a)when creating recovery volumes, the required disk space
  is preallocated in the beginning of operation. It helps to
  minimize the disk fragmentation;
  
  b) console RAR displays the operation percentage when creating
  recovery volumes or reconstructing missing or corrupt volumes.
  
• If "Save file security" option is enabled, folders will be
  archived after files which they contain. It is necessary to avoid
  the situation when security attributes of just unpacked folder
  do not allow to extract files to it.
  
• Optional description can be entered in "Add to favorite" dialog.
  If such description is available, WinRAR will display it
  in "Favorites" menu instead of folder or archive name.
