Download WinRAR 5.00 Beta 4

RAR Labs has released the fourth beta release of version 5.00 of its RAR and WinRAR archiving tools. The popular compression tool is available for a variety of operating systems, including Windows, Linux, and OS X. The program handles most common formats – including rar, zip, cab, arj, lzh, tar, gz, ace, uue, bz2, jar, iso, 7z and z – has a customizable interface, and support for Zip64 and multivolume cab files. The main change in version 5.00 is the introduction of a new compression format. This format, dubbed rar 5.0, generally produces smaller archives, but at the expense of speed. In beta 4 the following changes have been made:
