title: Is there some way of telling the IntelliJ IDEs like PyCharm that a specific file is of a specific format?
body: <p>For instance I can have two files with the same file ending:</p>
  
  <ul>
  <li>nginx.conf</li>
  <li>ossec.conf</li>
  </ul>
  
  <p>The first one is in nginx format, the second is XML. How do I force different highlights for each without renaming the files?</p>
