File archive containing one or more files compressed with RAR compression; uses a higher compression ratio than typical ZIP compression; incorporates a proprietary compression algorithm that is now used by other compressors, including 7-Zip for its .7Z files; may be extracted using a variety of programs.

More Information

The RAR compressor can also create spanned, or multi-volume, archives, which are split across several compressed files. These files typically have file extensions from ".R00" to ".R99," or they may all have the standard ".RAR" extension.

NOTE: The name "RAR" stands for "Roshal ARchive," which was named after Eugene Roshal, the RAR compression algorithm developer.
