Text file comparision software

[KuJaX]

Can someone recommend a program where I can compare two files (like text files, php files, etc) and the program will highlight or outline or tell me what differences there are between the two files.

This is used because I just got a lot of programming stuff done and I want to see exactly how the programmer did it, but I don't want to open up thousands of different files to look through them. :)

gnu diff, windiff, etc, etc. All depends on what you want (console, gui, IDE integration, free/gratis/commercial, etc)

Or, maybe Merge for Windows (http://www.araxis.com/merge/)

In the Benefits section it shows the following:

For code reviewers and auditors: identify in context every change made between two or three source code hierarchies. Create a standalone html or xml report of your findings. Add bookmarks and comments to a file or folder comparison, then save it as a single-file archive for emailing to other team members for review.
