The Unarchiver
Template:Short description Script error: No such module "Infobox".Template:Template other Script error: No such module "Check for unknown parameters".Script error: No such module "Check for conflicting parameters". The Unarchiver is an ad-supported[1] data decompression utility, which supports more formats than Archive Utility[2] (formerly known as BOMArchiveHelper), the built-in archive unpacker program in macOS. It can also handle filenames in various character encodings, created using operating system versions that use those character encodings.[3] The latest version requires Mac OS X Lion or higher. The Unarchiver does not compress files.[4]
Prior to the purchase by MacPaw in 2017,[5] The Unarchiver was free software licensed under the LGPL, up to version 3.11.1 (released 2016).[6] This version, and the versions prior to the buyout, are still available for download from Dag Ågren’s original website.[7] The Unarchiver version 3.11.1 provided a free-software implementation of extraction of RAR versions up to RAR5.[8][9]
The corresponding command line utilities unar and lsar are free software licensed under the LGPL[10][11] run on Microsoft Windows, Linux, and macOS.[12]
A key feature of The Unarchiver is its ability to handle many old or obscure archive formats, including StuffIt, AmigaOS disk images, and LZH/LZX archives. The source code credits libxad, an Amiga file format library. Ågren also reverse engineered the StuffIt and StuffIt X formats. His work resulted in one of the most complete open source implementations of these proprietary formats.
