Free software UnRAR

This version of Unrar[1] is free software, licenced under the GPL. It uses the GPL'd UniquE RAR Library unrarlib[2] by Christian Scheurer and Johannes Winkelmann, which is in turn based on an old version of RARLAB's UnRAR, with permission from author Eugene Roshal.^[1]

This application has been pushed to obsolescence due to the implementation of RAR3 format by RARLAB in their WinRAR archiver. The unrarlib library only supports RAR and RAR2 formats.^[2]

Overview

This program is a simple command-line front-end to this library, and can list and extract RAR archives. It does not rival the non-free unrar in terms of features, but special care has been taken to ensure it meets most user's needs. It was designed as a back-end for GUI archivers such as GNOME file-roller and KDE ark.

Freeware UnRAR

This UnRAR is distributed by RARLAB, the makers of the commercial WinRAR archivers. The source code as well as the binaries for a few dozen platforms are available for download on their website.^[3] The source code is not licenced under a free software license. It can extract newer RAR 3.x archives not supported by the free software Unrar.
