EViews.com

Often I work successively with colleagues at the same EViews program. It's easy to find out by eye-catching what they have changed since my last version, but if the program is too huge, it's hard to identify changes.
Could you recommend a program to compare the changes? So far I use to compare the files via the MS Office track changes option, but I'm not convinced that this is the best method. Any suggestions?

Purely a personal recommendation, and in no way an official endorsement, but I like Compare it!
