'''Szip''', AKA '''Sunzip'''&amp;lt;ref&amp;gt;V. 1.11 Windows/DOS distribution → README.TXT&amp;lt;/ref&amp;gt;, is a file compression utility and compressed file format. It was written by Michael Schindler. Due to changes in the program, there are actually 3 incompatible Szip formats&amp;lt;ref name=&amp;quot;newreadme&amp;quot;&amp;gt;V. 1.12a, source → readme&amp;lt;/ref&amp;gt;:&lt;br /&gt;
* the format used from v. 1.00 to v. 1.04;&lt;br /&gt;
* then, the format used in version 1.05X and its subversions (the &amp;quot;X&amp;quot; does not stand for anything; this is actually part of the version number&amp;lt;ref name=&amp;quot;history&amp;quot; /&amp;gt;);&lt;br /&gt;
* and then, the format used for version 1.10 (which came immediately after the 1.05Xs&amp;lt;ref name=&amp;quot;history&amp;quot; /&amp;gt;) and above.&lt;br /&gt;
&lt;br /&gt;
== Extensions ==&lt;br /&gt;
The author &amp;quot;recommend[s] using .sz for szipped files and .tar.sz or .tsz for szipped [[tar]]files&amp;quot;.&amp;lt;ref name=&amp;quot;newreadme&amp;quot; /&amp;gt; &amp;lt;!-- Convention seems to be that only .sz is listed in the infobox for this page, .tsz is on the Tar page, and .tar.sz is obvious enough that it can be ignored --&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Identification ==&lt;br /&gt;
Szip files start with {{magic|0x53 0x5a 0x0a 0x04}}.&amp;lt;ref&amp;gt;V. 1.11 Windows/DOS distribution → SZ_FORMT.TXT&amp;lt;/ref&amp;gt;&lt;br /&gt;
