title: Write Files to WPD device via MTP C#/VB.net
body: <p>I would like to write an application that will copy MP3 files to a SanDisk Sansa M240.  The SanDisk doesn't have a drive letter and uses MTP for file transfer. 
  I stumbled through the sample of connecting to the device at : <a href="http://blogs.msdn.com/dimeby8/archive/2006/09/27/774259.aspx" rel="nofollow noreferrer">http://blogs.msdn.com/dimeby8/archive/2006/09/27/774259.aspx</a></p>
  
  <p>but once connected, I can't figure out how to actually copy files / create folders on the device.</p>
  
  <p>I am very surprised that there aren't any .Net wrappers for this COM library.</p>
