'''Microsoft Help Viewer''', also known as&amp;lt;ref&amp;gt;http://kb.helpwaregroup.com/ms-help-viewer/hvinfo → Introduction, here called &amp;quot;MS Help 3&amp;quot;&amp;lt;/ref&amp;gt; '''Microsoft Help 3''', is a help format developed by Microsoft. It is much simplified compared to previous formats, with no project format or compiliation step; it is simply a [[ZIP]] file, renamed with the extension &amp;quot;.mshc&amp;quot; (&amp;quot;Microsoft Help Container&amp;quot;&amp;lt;ref&amp;gt;http://kb.helpwaregroup.com/ms-help-viewer/hvinfo#TOC-.MSHC-Microsoft-Help-Container---Help-file&amp;lt;/ref&amp;gt;), of the relevant resources, the main help pages being in [[XHTML]]&amp;lt;ref&amp;gt;http://hv2.helpmvp.com/doc/file-format&amp;lt;/ref&amp;gt;. There were two versions, &amp;quot;HV1&amp;quot; (2010&amp;lt;ref name=&amp;quot;wphist&amp;quot; /&amp;gt;) and &amp;quot;HV2&amp;quot; (2012&amp;lt;ref name=&amp;quot;wphist&amp;quot; /&amp;gt;), which are &amp;quot;basically the same[;] HV2 has a few more meta statements but these wont [sic] break backward compatibility.&amp;quot;&amp;lt;ref name=&amp;quot;hv2&amp;quot;&amp;gt;http://kb.helpwaregroup.com/ms-help-viewer/hv2info&amp;lt;/ref&amp;gt; The major difference between the versions was in the main implementation (and/or API) of the software that read them.&amp;lt;ref name=&amp;quot;hv2&amp;quot; /&amp;gt;&amp;lt;ref&amp;gt;http://mshelpwiki.helpmvp.com/mshelp/help-viewer&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The .mshc file might come alongside a pregenerated search index with the extension &amp;quot;.mshi&amp;quot;&amp;lt;ref&amp;gt;http://kb.helpwaregroup.com/ms-help-viewer/hvinfo#TOC-.MSHI-Microsoft-Help-Index---Index-fragment&amp;lt;/ref&amp;gt;; or also an [[HTML]] &amp;quot;Product Manifest file&amp;quot;, with the extension &amp;quot;.msha&amp;quot;&amp;lt;ref&amp;gt;http://kb.helpwaregroup.com/ms-help-viewer/hvinfo#TOC-.MSHA---Product-Manifest-file&amp;lt;/ref&amp;gt;, which specifies the organization of multiple .mshc files&amp;lt;ref&amp;gt;http://kb.helpwaregroup.com/ms-help-viewer/hvinfo#TOC-Packages-Books-Catalogs&amp;lt;/ref&amp;gt;. It might also be packed into a [[CAB]] file.&lt;br /&gt;
&lt;br /&gt;
Like [[Microsoft Help 2]], most uses of Microsoft Help Viewer mentioned online seem to extend to documentation of software development tools.&amp;lt;ref&amp;gt;https://docs.microsoft.com/en-us/visualstudio/help-viewer/overview?view=vs-2019&amp;lt;/ref&amp;gt;&lt;br /&gt;
