title: How to merge new files into another branch in TFS?
body: <p>Ok, in TFS we have a main <em>trunk</em> branch and another branch, let's call it <em>secondary</em>.  We have created a new file in the <em>trunk</em> but when trying to merge that specific file, it does not give us the option to merge to the <em>secondary</em> branch.  We're assuming that it's because an analagous file does not exist in secondary.</p>
  
  <p>Is this the cause of the problem and if so, how can we get that new file from the <em>trunk</em> into <em>secondary</em>?</p>
  
  <p>Here, we are merging a file that does exist in <em>secondary</em>.  As you can see, the dropdown lists all three of our branches (<em>secondary</em> is actually the middle one):

  <p>Now, when I try to merge a file which was created in <em>trunk</em> after <em>secondary</em> was branched, <em>secondary</em> is no longer listed as a target branch.
