VariCAD's native proprietary binary format is in the .DWB format. DWB files have the &amp;quot;{{magic|870100}}&amp;quot; beginning at byte 2. Byte one seems to indicate version. Version 7 header is &amp;quot;{{magic|32870100}}&amp;quot; Version 9 header is &amp;quot;{{magic|34870100}}&amp;quot;, the current version of VariCAD 2020, files begin with &amp;quot;{{magic|4C870100}}&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Starting in version 7, file format was changed.&amp;lt;ref&amp;gt;https://web.archive.org/web/19990219194439/http://www.varicad.com/news.htm&amp;lt;/ref&amp;gt;&lt;br /&gt;
