The person who asked for my help, had tried this. Some of the files are over 1000 lines in size, and trying to wade through the diff files was nearly impossible.

I wouldn't give up on diff though. You can use the -q switch which only outputs whether the files differ. By using some of the other diff switches (like -B which ignores changes whose lines are blank), you might be able to reduce the number of files that really differ.
