title: List files that are in the TFS repository but not in the Visual Studio solution
body: <p>We have big solution(300+ projets), which is evolving since a long time(7 years), and over the time, there has been a lot of refactoring(projects removed, moved, ...). We did notice that sometimes when some projects are deleted from the solution, they are not deleted from the solution, and also that we have some leftover files.</p>
  
  <p>We would like to find all those kind of files in order to delete most of them(not all).</p>
  
  <p>Is there a way to list all those files?
  (We have Visual Studio 2015 enterprise)</p>
