WinRar v3.80 WinRAR is a powerful archive manager. It can backup your data and reduce size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format.
Also WinRAR (a.k.a. RAR) is a shareware file archiver and data compression utility developed by Eugene Roshal. It is arguably one of the three main file archive programs for Windows, along with WinZip and 7-Zip. It is one of the few applications that is able to create RAR archives natively, as the encoding method is held to be proprietary.
