.rar

RAR compressed file or archive. A .rar file is a compressed file format, which can contain one or more files. The files are compressed and so take up less space than the originals, but can be uncompressed back to the original with no loss of data. Because of their small size .rar files are often uses for storage or transmission of files (such as across the internet).

RAR files are different to, but server a similar role to other compressed file formats such as .zip.

RAR archives may be split into several parts in which case subsequent files will have the file extension .r00, .r01, .r02 etc.
