title: Copy only difference (kdiff, winmerge, any diff like tool)
body: <p>Is there possibility of copy ONLY difference of two files? Like in winmerge, but, I can't find this option<img src="https://i.stack.imgur.com/yt8wu.png" alt="enter image description here"></p>
  
  <p>Just like on this screen- i want to copy only 'yellow part' . Of course I can do that manually, but in big file it's not too funny :-)</p>
