Dunno what OS’s it supports besides Windows but I use Kdiff for random comparisons regularly, I think it works pretty well untill you get to much larger files (20+ MB slows down a lot). The huge file wasn’t code but needed to check output changes for those curious.
I constantly check git comparison with previous versions to see what changed to break things in a build though. Didn’t know there was a way to diff any files in git,should probably just learn to use that one.
If you can’t beat 'em, swallow them.
