Tool for comparing game files?

[Akula4745]

Best my poor ol' brain can recall I read something about a tool for comparing files - to show differences side by side? Does something like this exist or is it just a figment of my imagination? Any help appreciated...

EDIT: Never mind... I found it. Mods feel free to delete this post.

Got me interested in it. What is it?

winmerge probably. Great tool for comparing any file in ascii text. That means cfg, ini, sns, eqp, upc, etc.

I use KDiff (http://kdiff3.sourceforge.net/)...simple and straightforward, imo...
