title: Comparing two folders for non identical files in CMD
body: <p>What I need to do is to compare two folders for non identical files in CMD with <code>DOS</code> commands.</p>
  
  <p>When I find non identical files, I need to write them into a .txt file with full path so I can find out where these files are actually contained.</p>
  
  <p>So how can I achieve this?</p>
