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. 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. Unicode is supported in archive filenames, allowing non-English filenames to be handled painlessly. You can manipulate the parameters of many archives at once and view a volume sequence as a single archive. WinRAR can convert other archive formats to RAR. It supports the Find command, allowing you to search for specified text and files in archives.
