title: How to undo changes in tfs coming from unmanaged workspace?
body: <p>I have a workspace that is lost forever. I have some files checked out from this workspace. I want to unlock them but I can't. I tried to do:</p>
  
  <pre><code>TF UNDO $/MyProject/MyFolder/MyFile.cs /WORKSPACE:LOST;user /s:http://mysite:8080
  </code></pre>
  
  <p>But I got this message:</p>
  
  <blockquote>
    <p>The workspace LOST;user is not on this
    computer.  Run get (get all if edits
    were undone) on the computer hosting
    that workspace to update it with the
    change s that have been made on the
    server.</p>
  </blockquote>
  
  <p>Does exist any way to undo a file (<strong>not every</strong> file) checked out by unavailable workspace?</p>
