title: Does Explorer's "virtual filesystem" have public API?
body: <p>Windows Explorer presents a virtual "filesystem", whose root is the Desktop folder, containing Recycle Bin and This/My Computer, which in turn contains mounted filesystems, Libraries, UPnP/MTP/PTP devices and Network Shortcuts. </p>
  
  <p><img src="https://i.stack.imgur.com/fxXJq.png" alt="Explorer"></p>
  
  <p>Given that the same layout can be observed in the builtin open/save/directory picker dialogs, one can assume that there's an (internal?) API exposing this "VFS". </p>
  
  <p>Is this the case? If yes, is such API public and can it be used from my own applications?</p>
