WinRAR is a shareware file archiver and data compression utility by Eugene Roshal. Pocket RAR, a version of the file archiver for the Pocket PC platform, is available as freeware. It is one of the few applications that are able to create RAR archives natively, as the encoding method is held to be proprietary.
