Most frequent use of this extension is to store compressed information archived using RAR format. It is a proprietary compression format developed by Eugene Roshal.

RAR usually compresses information better than other archivers but it takes slightly more time to perform compression. Closest competitor to RAR in compression ration is 7-Zip LZMA algorithm.

Note that it is impossible to view information inside of RAR archive without specific software. Following software is capable to open RAR files: WinRAR, 7-Zip, IZArc, PeaZip, Zipeg and ALZip.
