Free WinRAR alternatives
WinRAR is the only archiver that can create RAR-format archives. However, the creators of the format allow third-party developers to use the source code of their unpacker in their software. The following archivers are among free WinRAR alternatives capable of opening .rar archives:7-Zip
7-Zip is capable of creating archives in its own 7z format as well as in ZIP, GZIP, BZIP2 and TAR formats. The developers claim that their archiver can be used by everyone absolutely free of charge, even for commercial purposes. 7-Zip, unlike WinRAR, is not built into Windows Explorer; its interface is made in the classical file manager style by adding compression and decompression buttons.
