title: Fastest way to delete a tree of directories in batch file
body: <p>I need to write a batch file that received a directory that contains a huge number of empty sub-directories and deletes them all.</p>
  
  <p>What's the fastest way of doing this? (by fast I mean not like what Windows Explorer does when you try to delete such a directory...)</p>
  
  <p><strong>Clarification:</strong></p>
  
  <p>I'm not trying to delete <em>only</em> empty directories. It just so happens that this dir I'm trying to delete is mostly empty sub-dirs.</p>
