WinRAR is a 32-bit Windows version of RAR Archiver, an archiver and archive manager. RAR files can usually compress content 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, long filename support, programmable self-extracting archives (SFX), damaged archive repair, 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 is able to convert other archive formats to RAR. It supports the Find command, allowing search for specified text and files in archives.
The latest version features improved compression and speed, enhanced security options, support for additional archive types, and more.
