title: Ignore folders in PhpStorm
body: <p>How can I tell <a href="http://www.jetbrains.com/phpstorm/" rel="noreferrer"><strong><code>PhpStorm</code></strong></a> to <em>ignore folders</em> in a project?</p>
  
  <p><strong><em>e.g:</em></strong> I would like to ignore these folders for good without deleting them.</p>
