As said above if you are strictly looking to see if they match you could export the programs and bring them into a text editor (I use Notepad++) and compare. It will be hard to see the differences, but it will tell you if they are the same or not.
I need to compare the files so I can mark the differences and include them for reference in our ECR/ECO system. I also like to go over any changes I make prior to release so I can make sure that everything makes sense and is well documented. Habits I formed when I used to do embedded programming.
I will try the folder/text file(s) comparison and see how that works. It should be sufficient
I have the developers version of CCW. I would expect there would be a compare feature, but if there is, I must have missed it.
