title: SharePoint 2010 - User Photos and Sub Directorys
body: <p>When I open the user photo directory on my SharePoint 2010 in the Explorer.
  <a href="http://mysharepoint.de/User" rel="nofollow">http://mysharepoint.de/User</a> Photos/Profilbidler (Because it is German)
  I can see per user in the root directory 3 pictures in 3 different resolutions (32, 96, 144)</p>
  
  <p>But there are also 2 hidden directorys in this folder (_t and _w)</p>
  
  <p>In this folders are also 3 pictures with the resultions (32, 96, 144) from the same picture in the root directory.</p>
  
  <p>The name from a picture in the root directory is </p>
  
  <ul>
  <li>Domain_UserName_LThumb.jpg</li>
  <li>Domain_UserName_MThumb.jpg</li>
  <li>Domain_UserName_SThumb.jpg</li>
  </ul>
  
  <p>In both sub directorys:</p>
  
  <ul>
  <li>Domain_UserName_LThumb.jpg.jpg</li>
  <li>Domain_UserName_MThumb.jpg.jpg</li>
  <li>Domain_UserName_SThumb.jpg.jpg</li>
  </ul>
  
  <p>What is the reason for the directorys _w and _t?
  Are they necessary for the User Photos or only present because it is a SharePoint Photo Gallery?</p>
