title: Path prefixes \??\ and \\?\
body: <p>What is the difference between paths prefixed with <code>\??\</code> and those prefixed with <code>\\?\</code>      </p>
  
  <p>At Windows 7 CMD-Line                                                                    </p>
  
  <ul>
  <li>DIR gives:             <code>\??\Volume{00000000-0000-0000-0000-000000000000}\</code>                   </li>
  <li>WMIC VOLUME LIST gives <code>\\?\Volume{00000000-0000-0000-0000-000000000000}\</code></li>
  </ul>
  
  <p>Thanks                      </p>
  
  <p>Additional Information:<br>
  I created a directory on my system drive where i placed all my mount points into. So I did a <code>MD C:\HDDs</code> first, then a 
  <code>MD C:\HDD\Drive1</code>, <code>MD C:\HDD\Drive2</code> ...for all my drives. After mounting the drives on those empty directories, I can see the GUID by switching to that Directory with <code>CD /D C:\HDDs</code> and issueing a <code>DIR</code> command.  Maybe I have to issue a <code>DIR /ah</code> to Show hidden stuff, just in case the mount points are hidden directories ...</p>
