title: SVN: How to automagically remove the Working Copy but preserve ignored items?
body: <p>I currently have a Working Copy with two branches in it:</p>
  
  <pre><code>/Source
  /Source/v1.2
  /Source/v1.3
  </code></pre>
  
  <p>I want to delete this and instead only check out the branch I need (i.e. go one level down the directory tree and only check out /Source/v1.3).  However the working copy of v1.3 contains a bunch of ignored files that I actually want to keep.  So I don't want to just delete the whole working copy and start over.  And of course I don't want to manually try to locate all of the ignored files and preserve them.  Is there any sort of command to do this?</p>
  
  <p>I'm on Windows using TortoiseSVN as well as Slik SVN for automated builds.</p>
