title: Remove all local folder mappings for a TFS workspace using command line
body: <p>I can easily map/unmap working directories using tf.exe, but if a mapping to another folder, or the workspace root exists, this can still interfere with me mapping specific directories in a script.</p>
  
  <p>Is there a way to remove all working directory mappings from a workspace so I know I've got a "clean slate" to work from?</p>
