WinRAR 3.90 Beta 4 / 3.80 Stable

Major Features:

1. WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well.
2. WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).
3. WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executable and object libraries particularly well.
4. WinRAR allows you to split archives into separate volumes easily, making it possible to save them on several disks for example.
5. WinRAR is also ideal, if you are sending data through the web. Its 128 bit password encryption and its authenticated signature technology will give you the peace of mind you have been looking for.
6. WinRAR is shareware, meaning you have the chance to thoroughly test it. The program can be used absolutely free of charge for 40 days!
7. WinRAR licenses are valid for all available language and platform versions. If you have purchased several licenses, you can even mix versions to meet your own personal needs.

Enhancements: 

• 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.
• Added decompression support for WinZip AES encrypted ZIP archives.
• Improved Unicode support for RAR and ZIP archive names.
• "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:
• • switch -o enables "Ask before overwrite" archiving mode;
  • switch -o enables "Skip existing files" archiving mode;
  • switch -o+ enables "Overwrite all" mode (default for archiving).
  • New "Add to context menu" option in "Profile parameters" dialog.
