DIARBYRAG  This program is just what I needed to compare my local copy to a clients online zen cart site. great time saver. works just fine and any differences are easy to find

thankyou to the developers for such a great free program

BOZO CLOWN  Awesome tool! Merge individual files or entire source trees with ease. DiffMerge wins because I can work much more quickly with it than with FileMerge because there's never any doubt what the merged file is going to have in it. The only feature I can think of adding is a context menu option to copy missing files from one tree to the other. Recommended!

EAN  Wow. And free. A very nice diff tool. I only wish I could switch the files back and forth between the source and edit panels iin edit mode with out having to reload the files or open another window or anything. It's picky, but the toolbar icons two diff-erent states should be more readily noticable. More contrast in the icon, or something.
