WinRAR is available on Windows, OSX, and Linux, despite the name. While RAR files are not native to Windows or Mac, many other compression programs are still capable of unpacking it. Its RAR format may only take second place for its level of compression but it is consistently the fastest when it comes to both packing and unpacking files. WinRAR is a powerful archive manager providing complete support for RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives.
