Rar

In computing, RAR is a compressed archive format developed by Eugene Roshal. His main product is WinRAR, which is shareware. Pocket RAR, a version of the RAR archiver for the Pocket PC platform, is available as freeware.

Eugene Roshal has also released source code for decoding RAR archives, under a licence that allows free distribution and modification, but forbids its use to build a compatible encoder. However, this version can only extract RAR version 2.x archives, not archives that are encoded with RAR 3.x. The encoding method is held to be proprietary.

The file extension is .rar. The MIME-Type is application/x-rar-compressed.
