StuffIt Expander is a proprietary,freeware,closed source,decompression software utility developed byAllume Systems (a subsidiary ofSmith Micro Software formerly known as Aladdin Systems). It runs on theclassic Mac OS,macOS, andWindows. Prior to 2011, aLinux version had also been available for download.
The latest version for each Mac platform is as follows:[1]
StuffIt has been a target of criticism and dissatisfaction from Mac users in the past as the file format changes frequently, notably during the introduction of StuffIt version 5.0. Expander 5.0 contained many bugs, and its file format was not readable by the earlier version 4.5, leaving Mac users of the time without a viable compression utility.
The lateststand-alone version forWindows is 2011 (15.0). Unlike the version before it (12.0), which was only able to decompress the newer.sitx (andZIP) archives, version 2009 claims to be able to decompress over 30 formats, some listed below. The executables require both, the.NET v2.0 framework andMSVC 2008 (9.0) runtimes. The previous stand-alone version able to decompress.sit and otherclassic Mac OS-specific archives was 7.02, distributed withStuffIt v7.0.x forWindows.
From versions 7.5.x to 11 the Expander capabilities were actually performed by theStuffIt Standard Edition, that allowed decompression even after the end of the trial period. To startStuffIt in Expander mode the following command line switches were used:-expand -uiexpander.[3] Note that the registration reminder dialogue box is not shown in this case. With older versions of StuffIt Expander on the classic Mac OS platform, such as StuffIt Expander 3.5, it was possible to enhance the capabilities of StuffIt Expander and to add support for decompressing additional archive formats by means of the shareware DropStuff with Expander Enhancer software from Aladdin Systems.[4]
An officialMS-DOScommand line program, UNSTUFF v1.1, can decompress.sit files.
StuffIt Expander 2009 decompresses files in the following formats:
