StuffIt Expander
open-in-new
<p>StuffIt Expander is a proprietary, <a href="/facts/Freeware/c8oGA9ju">freeware</a>, <a href="/facts/Closed_source/9zcskxYL">closed source</a>, <a href="/facts/Data_compression/gMFuY4FT">decompression</a> software utility developed by <a href="/facts/Allume_Systems/N98dYGCk">Allume Systems</a> (a subsidiary of <a href="/facts/Smith_Micro_Software/YnKkpoVN">Smith Micro Software</a> formerly known as Aladdin Systems). It runs on the <a href="/facts/Classic_Mac_OS/I5fQq44K">classic Mac OS</a>, <a href="/facts/MacOS/Y93vVpTm">macOS</a>, and <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a>. Prior to 2011, a <a href="/facts/Linux/9FvCKSTq">Linux</a> version had also been available for download. </p><p>The latest version for each Mac platform is as follows: </p> <ul><li>16.2 for <a href="/facts/OS_X_10.11/4NAIbG7c">OS X 10.11</a>+ (as of December 2020);</li> <li>16.0.5 for <a href="/facts/Mac_OS_X_10.8/GIu66667">Mac OS X 10.8</a>+;</li> <li>15.0.7 (2011) for <a href="/facts/Mac_OS_X_10.6/GGNogRTe">Mac OS X 10.6.8</a>+;</li> <li>15.0.4 (2011) for <a href="/facts/Mac_OS_X_10.5/UmXw4H5x">Mac OS X 10.5</a>+;</li> <li>14.0.1 (2010) for <a href="/facts/Mac_OS_X_10.4/q6vKCpvq">Mac OS X 10.4</a>+;</li> <li>10.0.2 for <a href="/facts/Mac_OS_X_10.3/lDrnzKAe">Mac OS X 10.3</a>+;</li> <li>8.0.2 for <a href="/facts/Mac_OS_X_10.0/twuQ9J75">Mac OS X 10.0</a>+;</li> <li>7.0.3 for <a href="/facts/Mac_OS_8/Vde5S5hl">Mac OS 8.6</a>+;</li> <li>6.0.1 for <a href="/facts/Mac_OS_8/Vde5S5hl">Mac OS 8.1</a>+ (PowerPC only);</li> <li>5.5.1 for <a href="/facts/Macintosh_System_7/IwLKo2sX">System 7.1</a>+ (68020 and up, PowerPC);</li> <li>4.5 for <a href="/facts/System_6/5hKYcxEV">System 6</a>+ (compatible with all 68k processors).</li></ul> <p>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. </p><p>The latest <a href="/facts/Standalone_program/2KduaAxh">stand-alone</a> version for <a href="/facts/Microsoft_Windows/bwhAhuSL">Windows</a> is 2011 (15.0). Unlike the version before it (12.0), which was only able to decompress the newer <a href="/facts/Stuffit/MEIyJKJ8">.sitx</a> (and <a href="/facts/ZIP_(file_format)/qDrrYIB9">ZIP</a>) archives, version 2009 claims to be able to decompress over 30 formats, some listed below. The executables require both, the <a href="/facts/.NET_Framework/J6QDAUhP">.NET v2.0 framework</a> and <a href="/facts/Visual_Studio_2008/omNe6Lej">MSVC 2008 (9.0)</a> runtimes. The previous stand-alone version able to decompress <a href="/facts/.sit/MEIyJKJ8">.sit</a> and other <a href="/facts/Classic_Mac_OS/I5fQq44K">classic Mac OS</a>-specific archives was 7.02, distributed with <a href="/facts/StuffIt/MEIyJKJ8">StuffIt</a> v7.0.x for <a href="/facts/Microsoft_Windows/bwhAhuSL">Windows</a>. </p><p>From versions 7.5.x to 11 the Expander capabilities were actually performed by the <a href="/facts/StuffIt/MEIyJKJ8">StuffIt Standard Edition</a>, that allowed decompression even after the end of the trial period. To start <a href="/facts/StuffIt/MEIyJKJ8">StuffIt</a> in Expander mode the following command line switches were used: -expand -uiexpander. 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. </p><p>There is also a <a href="/facts/Command_line_interface/R9JpGmXQ">command line</a> <a href="/facts/DOS/sWwDXNmX">DOS</a> application called UNSTUFF v1.1 that allows decompression of <a href="/facts/.sit/MEIyJKJ8">.sit</a> files. </p><p>StuffIt Expander 2009 decompresses files in the following formats: </p> <ul><li><a href="/facts/7z/qG1rNuWr">7-Zip</a> (.7z, <a href="/facts/Comic_Book_Archive_file/meuWRWGz">.cb7</a>)</li> <li><a href="/facts/AppleSingle/mY86Lr5k">AppleSingle</a> (.as)</li> <li><a href="/facts/ARC_(file_format)/Ymtby6g4">Arc</a> (.arc)</li> <li><a href="/facts/ARJ/PPXbE4mq">ARJ</a> (.arj)</li> <li><a href="/facts/BinHex/9XqEhCjL">BinHex</a> (.hqx), all versions</li> <li><a href="/facts/Binary-to-text_encoding/InSaUsBb">BTOA</a> (.b2a, .btoa)</li> <li><a href="/facts/Bzip2/waffQ2m0">bzip2</a> (.bzip, .bzip2, .bz, .bz2, .tbz, .tbz2, .tar.bz, .tar.bz2)</li> <li><a href="/facts/Cabinet_(file_format)/NIKLUQyz">CAB</a> (.cab)</li> <li><a href="/facts/Compact_Pro/1fkxyd3t">Compact Pro</a> (.cpt)</li> <li><a href="/facts/Gzip/H23uqvyx">gzip</a> (.gz, .tgz)</li> <li><a href="/facts/LHA_(file_format)/e7r4UwDo">LHA</a> (.lha, .lzh)</li> <li><a href="/facts/LZMA/XMBm3MBK">LZMA</a> (.lzma, .tlzma, .tar.lzma)</li> <li><a href="/facts/MacBinary/1dIfr23C">MacBinary</a> (.bin, .macbin), all versions</li> <li><a href="/facts/Base64/xIvVm33q">MIME/Base 64</a> (.mime)</li> <li>Private File (.pF), Aladdin's <a href="/facts/Encryption/16q29Fdv">encryption</a> file format</li> <li><a href="/facts/RAR_(file_format)/cgHI6gnw">RAR</a> (.rar, .rNN, <a href="/facts/Comic_Book_Archive_file/meuWRWGz">.cbr</a>, .partNN.rar), including segmented</li> <li>SpaceSaver StuffIt compression format used in versions prior 5.x</li> <li><a href="/facts/StuffIt/MEIyJKJ8">StuffIt</a> (.sit, .sitx, .sit.N, .partNN.sitx, .sea, .exe) v1.5.1 to 8.0.x, including encrypted, segmented and <a href="/facts/Self-extracting_archive/xTq54ltw">self-extracting archive</a> (Classic Mac OS file type code 'SIT!')</li> <li><a href="/facts/Tar_(file_format)/DCJ37j3d">tar</a> (.tar, .gtar, .gnutar, .ustar, <a href="/facts/Comic_Book_Archive_file/meuWRWGz">.cbt</a>)</li> <li>Unix <a href="/facts/Compress/RLSgGNUX">Compress</a> (.Z, .z, .taz)</li> <li><a href="/facts/Uuencoding/lEjGENqK">UU</a> (.uu, .uue, .enc), PC/Unix 8 bit to 7 bit encoding similar to BinHex (.hqx)</li> <li><a href="/facts/YEnc/oNXtjfEp">yEncode</a> (.ync, .y)</li> <li><a href="/facts/ZIP_(file_format)/qDrrYIB9">ZIP</a> (.zip, .zNN, <a href="/facts/Comic_Book_Archive_file/meuWRWGz">.cbz</a>, .exe), including encrypted, Zip64, segmented and <a href="/facts/Self-extracting_archive/xTq54ltw">self-extracting archive</a></li></ul>
