title: How to copy queries by folder in Team Explorer's Work Items pan
body: <p>In Visual Studio(2015 Update 3) I want to copy all my TFS work item queries.<br>
  The queries are placed in multiple nested folders hierarchically.<br>
  As I remember, I used to do this task simply by copying the top level folder.<br>
  However,recently I noticed that the Copy functionality is not available for folders as it is grayed out in their context menu.  </p>
  
  <p>Whats the workaround?</p>
  
  <p>By the way any solution using TFS Sdk is welcomed. </p>
