WinRAR is a 32-bit Windows version of RAR Archiver, an archiver and archive manager. RAR files can usually compress content by 8 percent to 15 percent more than ZIP files can. WinRAR's main features include strong general and multimedia compression, the ability to process non-RAR archive formats, ZIP compression and decompression, support for long filenames, programmable self-extracting archives (SFX), repair of damaged archives, authenticity verification, embedded file comments, and encryption.
