They split the product line in two, offering <b>StuffIt Classic</b> in <a href="/wiki/Shareware" title="Shareware">shareware</a> and <b>StuffIt Deluxe</b> as a commercial package. Deluxe added a variety of additional functions, including additional compression methods and integration into the Mac Finder to allow files to be compressed from a "Magic Menu", or seamlessly browse inside and edit compressed files without expanding them using "True Finder Integration".<a rel="nofollow" class="external autonumber" href="http://www.stuffit.com/guide/SDX2011M/MagicMenu.html">[1]</a> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20130222090439/http://www.stuffit.com/guide/SDX2011M/MagicMenu.html">Archived</a> 2013-02-22 at the <a href="/wiki/Wayback_Machine" title="Wayback Machine">Wayback Machine</a> </p><p>StuffIt was upgraded several times, and Lau removed himself from direct development as major upgrades to the "internal machinery" were rare.

This move was a success, and Compact Pro subsequently fell out of use. </p><p>Several other Mac compression utilities appeared and disappeared during the 1990s, but none became a real threat to StuffIt's dominance. The only ones to see any widespread use were special-purpose "disk expanders" like <a href="/wiki/DiskDoubler" title="DiskDoubler">DiskDoubler</a> and SuperDisk!, which served a different niche. Apparently as a side-effect, StuffIt once again saw few upgrades. The <a href="/wiki/File_format" title="File format">file format</a> changed in a number of major revisions, leading to incompatible updates. PC-based formats long surpassed the original StuffIt format in terms of compression, notably newer systems like <a href="/wiki/RAR_(file_format)" title="RAR (file format)">RAR</a> and <a href="/wiki/7z" title="7z">7z</a>.

It was designed to be extendable, support more compression methods, support long file names, and support Unix and Windows file attributes. StuffIt X improves over the original StuffIt format and its descendants by adding multiple compression algorithms such as <a href="/wiki/PPM_compression_algorithm" class="mw-redirect" title="PPM compression algorithm">PPM</a>, and <a href="/wiki/Burrows%E2%80%93Wheeler_transform" title="Burrows–Wheeler transform">BWT</a> to <a href="/wiki/LZW" class="mw-redirect" title="LZW">LZW</a>-type compression. It also added a "block mode" option, error correcting "redundancy" options to protect against data loss, and several encryption options. In January 2005, <a href="/wiki/JPEG" title="JPEG">JPEG</a> compression was added as a StuffIt X compression option (see the related 'SIF Format' below). </p><p>From the mid-1990s until the 2005 acquisition by <a href="/wiki/Smith_Micro_Software" title="Smith Micro Software">Smith Micro Software</a>, coinciding with the release of <a href="/wiki/Mac_OS_X_v10.4" class="mw-redirect" title="Mac OS X v10.4">Mac OS X v10.4</a> "Tiger," StuffIt Expander came bundled with the Macintosh operating system. </p><p>Although Mac files generally did not use <a href="/wiki/Filename_extension" title="Filename extension">filename extensions</a>, one of StuffIt's primary uses was to allow Mac files to be stored on non-Mac systems where extensions were required. So, StuffIt-compressed files save the resource forks of the Macintosh files inside them, and typically have the extension <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r886049734"><span class="monospaced">.sit</span>. Newer (non-backwards compatible) <b>Stuffit X</b>-compressed files carry the file extension <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r886049734"><span class="monospaced">.sitx</span>. Encrypted StuffIt archives created with the now-discontinued <i>Private File</i> utility will have <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r886049734"><span class="monospaced">.pf</span> extensions. StuffIt-compressed <i>ShrinkWrap</i> <a href="/wiki/Disk_image" title="Disk image">disk images</a> will carry <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r886049734"><span class="monospaced">.img</span> or <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r886049734"><span class="monospaced">.image</span> extensions. However, a <a href="/wiki/Classic_Mac_OS" title="Classic Mac OS">Classic Mac OS</a> version of StuffIt is needed to mount the images or convert them to a newer format readable in <a href="/wiki/MacOS" title="MacOS">macOS</a>. </p><p><a href="/wiki/Smith_Micro_Software" title="Smith Micro Software">Smith Micro Software</a> offers free downloads of <a href="/wiki/StuffIt_Expander" title="StuffIt Expander">StuffIt Expander</a> for Mac and Windows, which expands (uncompresses) files compressed using the StuffIt and StuffIt X format, as well as many other compressed, encoded, encrypted and segmented formats. The <a href="/wiki/Shareware" title="Shareware">shareware</a> application <a href="/w/index.php?title=DropStuff&action=edit&redlink=1" class="new" title="DropStuff (page does not exist)">DropStuff</a> permits the compressing of files into the StuffIt X format. </p><p>The StuffIt and StuffIt X formats remain, unlike some other file compression formats, <a href="/wiki/Proprietary_format" class="mw-redirect" title="Proprietary format">proprietary</a>, and <a href="/wiki/Smith_Micro_Software" title="Smith Micro Software">Smith Micro Software</a> charge license fees for its use in other programs. Given this, few alternative programs support the format. </p><p>There was also a "self-expanding" variant of StuffIt files with a <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r886049734"><span class="monospaced">.sea</span> extension that runs as an executable.

Programs that optimize JPEGs without regard for the original file, only the original image, obtain compression rates from 3 to 10% (depending on the efficiency of the original JPEG). Programs that use the rarely implemented <a href="/wiki/Arithmetic_coding" title="Arithmetic coding">arithmetic coding</a> option available to the JPEG standard typically achieve rates around 12%.) </p><p>The new technique was implemented as a StuffIt X format option in their <i>StuffIt Deluxe</i> product. They have also proposed a new image format known as SIF, which simply consists of a single JPEG file compressed using this new technique. </p><p>Pending filing of their patent, they retain knowledge of the details of this algorithm as a trade secret. Some details are disclosed in:<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> the high JPEG recompression is achieved by undoing the last step of the JPEG compression itself (the Huffman encoding of quantized transform coefficients). Instead, the transform coefficients are compressed by a more efficient algorithm (a predictive model based on the DC coefficients of neighboring blocks). Similar techniques are also applied for other image file formats such as GIF and TIFF and even the MP3 music file format. By means of decomposition, the relatively high compression rates for individual file formats can also be achieved for container file formats such as PDF, PSD and even ZIP. </p> <div class="mw-heading mw-heading3"><h3 id="StuffIt_Wireless">StuffIt Wireless</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=StuffIt&action=edit&section=4" title="Edit section: StuffIt Wireless"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>On July 5, 2005, <a href="/wiki/Smith_Micro_Software" title="Smith Micro Software">Smith Micro Software</a> announced their acquisition and intention to expand the new JPEG recompression technique to wireless platforms and other file formats.
