Copy only difference (kdiff, winmerge, any diff like tool)

Is there possibility of copy ONLY difference of two files? Like in winmerge, but, I can't find this optionenter image description here

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 :-)

Solution

  • WinMerge has a built-in and simple way to generate such "diff only" files, that they called "patches".

    Click on "Tool", then on "Generate Patch...", and enter where you want to store the result:

    enter image description here

    You will obtain (for your example) the file

    4,8c4,8
< HELLO WORLD
< HELLO WORLD
< HELLO WORLD
< HELLO WORLD
< HELLO WORLD
---
> 
> 
> 
> 
>

    That uses the standard, compact way of representing diff and is easy to manipulate.
