File type: WinRAR Compressed Archive.
The RAR file extension is the file extension used to refer to compressed archives proprietarily using this archiving format.

This file format was developed by Eugene Roshal, a Russian programmer. The RAR files also require a longer time to compress, although they have higher compression ratio compared to other archiving formats, like the GZIP or ZIP file extensions.
The improvement in the compression made using this file extension depends mainly on the files being compressed. Currently, the files using the file extension RAR may only be created with commercial software applications like Squeeze or WinRAR. Both applications are only available on the Windows Operating System.
