Araxis Merge 6.5

Awesome! If you need to compare and synchronize files from 2 or 3 different directory trees, you need this. It is actually a developer's tool even more than a sys admin tool because of its byte-for-byte comparison capability that tracks changes between versions of the same file. I got it to try because a critical backup process had failed and time was too short to rerun the entire backup. Merge 2008 let me get things back on track in a quarter of the time. I STRONGLY recommend!
