I find Araxis Merge especially useful in these times. This application has a feature to &quot;set the synchronization link&quot; at any place you want in the code. It is not automatic (or language aware), but once you realize the difference, you can &#x27;fix&#x27; the diff in real time. That helped me a lot for big diff files (unfortunately in my current company we don&#x27;t use Araxis :( )
