WinRAR is a 32-bit version of RAR, the powerful archive manager. RAR files can normally compress files up to 10 percent more than ZIP or ARJ files. It provides complete support of RAR and ZIP files, unpacks 7Z, ACE, ARJ, BZ2, CAB, GZ, ISO, JAR, LZH, TAR, UUE, Z. Among WinRAR features are strong compression, volumes, encryption, self-extracting modules, backup facilities.

Version 3.80

1. Added support for ZIP archives containing Unicode file names
in UTF-8 format. When creating ZIP archive, WinRAR stores
names in Unicode only if they cannot be stored correctly using
the current single byte character set.

2. Added decompression support for WinZip AES encrypted ZIP archives.

3. Improved Unicode support for RAR and ZIP archive names.

4. "Ask before overwrite" and "Skip existing files" update modes
are now available in archiving dialog. They allow to specify
WinRAR behavior when updating already existing files in archive.
Unlike already available "Fresh existing files only" and
"Add and update files", these new modes ignore file date
and compare only file names.

Command line equivalents of these modes are:

a) switch -o enables "Ask before overwrite" archiving mode;

b) switch -o- enables "Skip existing files" archiving mode;

c) switch -o+ enables "Overwrite all" mode (default for archiving).

5. New "Add to context menu" option in "Profile parameters" dialog.
If this option is on, the profile name will be displayed in Explorer
context menus allowing to activate a profile from context menu.

6. New -cp switch allows to select a compression profile
in command line mode. It is supported only by GUI WinRAR.exe,
not by rar.exe.

7. New "Options" page of archiving dialog contains the group of
settings modifying the behavior of "Delete files after archiving"
option from "General" page:

a) Delete files. Delete files normally like in previous WinRAR
versions.

b) Move files to Recycle Bin. Deleted files are placed to
Recycle Bin.

Command line equivalent of this option is -dr switch.

c) Wipe files. Before deleting file data are overwritten by
zero bytes to prevent recovery of deleted files.

Command line equivalent of this option is -dw switch.

All these options have an effect only if "Delete files
after archiving" is on. You can enable any of these options
in the default compression profile to change the default
behavior of "Delete files after archiving".

8. WinRAR "Extraction path and options" dialog is now resizable.
You can use the mouse to drag its border to the desired size
and provide more space for folder tree pane. WinRAR will store
new dimensions of this dialog.

9. New "Update" SFX script command and "Update mode" group
of options in "Update" page of "Advanced SFX options" dialog.
These command and options allow to check time and implement
file time based updating;

10. SFX script "Shortcut" command and "Add shortcut..." command
in "Advanced SFX options" dialog now allow to specify
an icon file containing an icon associated with shortcut.

11. New "Wipe temporary files" option in "Settings/Security" dialog
provides more secure, though slower, way to delete temporary
WinRAR files.

12. WinRAR and RAR display the total progress bar when unpacking
a multivolume RAR archive if all volumes are present
in the same folder.

13. WinRAR and RAR automatically expand names of environment
variables in list files. For example, a list file can contain
lines like:

%windir%\*.exe
%USERPROFILE%\Desktop

This feature is available only in Windows RAR version.

14. Added support of TAR archives with non-zero "extra field" data.

15. Added support of TAR archives, which does not contain
the end of archive entry consisting of 512 zero bytes.

16. Improved Unicode support when dragging files from WinRAR window.

17. Shift+Tab key combination can be used in main WinRAR window to
switch the input focus between interface elements (files, comment,
tree, address) in reverse order. In previous versions Shift+Tab
used the same order as Tab.

18. Corrected a possible WinRAR crash when opening truncated
UDF ISO files.
