<p>ChristoCoder: Fixed source code link, site was dead</p> <hr /> <div>{{FormatInfo<br /> |formattype=electronic<br /> |subcat=Compression<br /> |extensions={{ext|F}}, {{ext|f}}<br /> }}<br /> '''Freeze''' is a file compression utility used from the command line in Unix-style operating systems. '''Melt''' is the corresponding decompressor. It is considered obsolete now in favor of [[gzip]].<br /> <br /> A two-pass compression is done with a [[Lempel-Zev]] algorithm on the first pass and a dynamic [[Huffman coding|Huffman algorithm]] on the second. The characteristics of the Huffman table used are added to the file. File attributes, ownership, etc., are preserved, and a .F extension is added. A two-byte magic number is prepended to the file (\037\236 octal for versions 1.x, and \037\237 for later versions).<br /> <br /> == References ==<br /> * [http://www.esrl.noaa.gov/gmd/dv/hats/cats/stations/qnxman/freeze.html Man page] (in NOAA site, which should know something about freezing!)<br /> * [http://ibiblio.org/pub/linux/utils/compress/freeze-2.5.0.tar.gz/ Source code]<br /> <br /> [[Category:File formats with case sensitive extensions]]</div>

<p>ChristoCoder: Added CLI download link</p> <hr /> <div>{{FormatInfo<br /> |formattype=electronic<br /> |subcat=Archiving<br /> |extensions={{ext|uha}}<br /> |released=1997<br /> }}<br /> <br /> '''UHARC''' is a compression/archiving system for PC platforms, which appears to be neglected since around 2005. It achieves better compression than most other archivers, at the expense of being much slower.<br /> <br /> == Links ==<br /> * [[Wikipedia:UHARC|Wikipedia article]] (rather minimal)<br /> * [http://ftp.sac.sk/pub/sac/pack/uharc06b.zip Download (CLI version)]<br /> * [http://www.softpedia.com/get/Compression-tools/UHARC-GUI-by-Brhack.shtml Download (GUI version)]<br /> * [http://www.youtube.com/watch?v=GPSbmKv3CqA UHARC tutorial video] (with annoying music)</div>

It is a more size-efficient alternative to [[Uuencoding]].<br /> <br /> It is justly characterized as &quot;quick and dirty&quot;, requiring crude Uuencoding-style heuristics to detect it, instead of utilizing the robust-but-complex [[MIME]] standard that predates it.<br /> <br /> == Specifications ==<br /> [http://www.yenc.org/yenc-draft.1.3.txt yEncode - A quick and dirty encoding for binaries v1.2] (.txt file)<br /> <br /> == Identification ==<br /> A yEnc-encoded file is delimited by lines that begin with &quot;&lt;code&gt;=ybegin&lt;/code&gt;&quot; and &quot;&lt;code&gt;=yend&lt;/code&gt;&quot;.<br /> <br /> == Links ==<br /> * [http://www.yenc.org/ yEnc Homepage]<br /> * [[Wikipedia:YEnc|Wikipedia article]]<br /> <br /> [[Category:E-Mail, newsgroups, and forums]]</div>
