title: Untracked files in git while checkout
body: <p>When I try to checkout to my bryan branch from my master branch, I get this message:</p>
  
  <pre><code>error: The following untracked working tree files would be overwritten by checkout:
      Manager/InvoicingAdslManager.php
  Please move or remove them before you can switch branches.
  Aborting
  </code></pre>
  
  <p>If I remove this untracked file, does it disappear from my bryan branch? </p>
  
  <p>Would be awesome if annyone could explain.</p>
