title: How do I undo "svn switch" on a subdirectory?
body: <p>Not for the first time, I've accidentally done "svn switch" from somewhere below the root of my project. This switches that subdirectory only, but how do I undo this?</p>
  
  <p>If I try switching the subdirectory back to the original branch I get:</p>
  
  <pre><code>"svn: Directory 'subdir\_svn' containing working copy admin area is missing"
  </code></pre>
  
  <p><strong>Update</strong>: I've got changes in the subdir, so I don't want to do a delete. </p>
  
  <p>In the short term I've fixed it by reapplying the changes, but I was after a way to get Subversion to re-switch back to where I came from... or is this a missing feature?</p>
