WinRAR is a powerful compression tool with many integrated additional functions to help you organize your compressed archives.

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.

Features:

• WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).
• WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries particularly well.
• WinRAR allows you to split archives into separate volumes easily, making it possible to save them on several disks for example.
• 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.
• WinRAR is shareware, meaning you have the chance to thoroughly test it. The program can be used absolutely free of charge for 40 days!
• 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.
• WinRAR gives you all future UPDATES for FREE!

What's New:

• If archiving operation cannot allocate memory required for compression dictionary, it automatically reduces the dictionary size.

• Decompression algorithm can store the dictionary in several memory blocks. It helps to unpack an archive on systems with high level of memory heap fragmentation, when no single memory block is large enough to fit the entire compression dictionary.

• Fixed XZ archive support, which did not work in beta 2.

• "Convert" command did not allow to use compression dictionaries exceeding 4 MB.
• If both encryption password and archive comment were specified when creating RAR archive, archive comment was not added.
• "View as Unicode (UTF-8)" command in internal viewer did not work, so UTF-8 files were displayed correctly only if their encoding was detected by viewer automatically.
• Maximum compression dictionary size when running in Windows XP x86 is reduced to 128 MB. WinRAR cannot allocate enough memory to create archives with 256 MB dictionary in Windows XP x86.
• Corrections in relative path processing, such as "..arcname.rar" name in archiving dialog or "WinRAR foldername" in the command line.
