title: Accessing MTP vendor extended properties through WPD
body: <p>I am using Windows Portable Device API to access some MTP devices. I want to read the vendor extended properties from the device, it should look something like this:</p>
  
  <p>"microsoft.com/WPDNA" or "microsoft.com/MTPZ"</p>
  
  <p>It seems like this should be a quite simple task but I cannot figure it out.</p>
  
  <p>I have been able to enumerate objects on a device and transfer files and so on, this was included in the <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/dd389001(v=vs.85).aspx" rel="nofollow">WpdApiSample Application</a>.</p>
  
  <p>I also found <a href="https://blogs.msdn.microsoft.com/dimeby8/2006/10/17/accessing-mtp-vendor-extended-properties-through-wpd/" rel="nofollow">this article</a> that I think is what I want to do. But I don't understand how to create those queries.</p>
