title: Find and rename files with no extension?
body: <p>So, I've got a bunch of files with no extension.  I want to write a windows batch script that will:</p>
  
  <ol>
  <li>Find files with no extension (in a specified folder)</li>
  <li>Add .bla to the end of the file name</li>
  </ol>
  
  <p>I'm such a windows batch script noob I don't even know where to start.  Suggestions?</p>
