WinRAR features page.

• 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.

• WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).

• WinRAR supports files and archives up to 9,223,372,036,854,775,807 bytes in size, about 9000PB. The number of archived files is, for all practical purposes, unlimited.

• WinRAR supports NTFS file security and data streams.

• WinRAR provides functionality for creating a 'solid' archive, which can raise the compression ratio by 10% - 50% over more common methods, particularly when packing large numbers of small files.

• 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 offers the ability to create a multi-volume archive as SFX.

• 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 for Pocket PC is also available free of charge.

• WinRAR available in English, Hungarian, Slovenian, Hebrew, Macedonian, Dutch, French, Serbian Cyrillic, Serbian Latin, Traditional Chinese, Portuguese Brazilian, Japanese, Korean, Portuguese, Polish, Swedish, Lithuanian, Danish, Croatian, Turkish, Albanian, Russian, Bosnian, Persian, Romanian.

• WinRAR gives you all future UPDATES for FREE! Not like the competition that will make you pay again every one or two years.
