title: What is "Miscellaneous Files" inside DTE VS2010 Solution?
body: <p>Following up on my previous question:
  <a href="https://stackoverflow.com/questions/6410911/vs2010-dte-addin-project-inside-solution-folder-is-not-project">VS2010 DTE Addin: project inside solution folder is not &quot;Project&quot;</a>
  I successfully found all my projects in the solution. However, the code also founds an extra item named "Miscellaneous Files". It's <code>Kind</code> is different to the solution folders and the projects as well, but there are no more constant kinds fixed in the <code>ProjectKinds</code> class (for that matter there isn't one for "Projects" either...)</p>
  
  <ul>
  <li><strong>What is this item?</strong></li>
  <li><strong>Should I be concerned about this?</strong>   </li>
  <li><strong>Why are there no more constants in</strong> <code>ProjectKinds</code><strong>?</strong></li>
  </ul>
