title: Edit diff files
body: <p>I have a <code>.diff</code> file generated from comparing two directories. However, there are some folders and files that appear in the <code>.diff</code> that I want to remove from it, so I can get a cleaner <code>.diff</code>. </p>
  
  <p>Is there any editor that lets me do this (something like Kompare, but it must allow to remove files from the diff)? How can I specify to exclude specific directories?</p>
