Comparing Folders

I used a utility called ABCommander in Windows that let me compare two folders (and I could synchronise them if I chose). I don't care so much about the latter feature, though it would be nice, but I still need to compare folder contents a lot. I can't figure out how to do it in Finder. Is there a way? If not, can anyone recommend a mac program to do it? Free or paid, irrelevant. I have googled and found iNexus Compare Folders but wonder if anyone has it and has anything to say about it.

Would this work?

It's got a 30 day trial so you can play around with it

Thanks, Chris

I think it is way more powerful and complex than I need but it sure looks like a dynamite piece of software. If I have to buy, the $29 iNexus is looking far more likely than the $129 Araxis

I am fooling with iNexus right now (they have a very limited trial download) and it isn't even close to ABCommander but it may have enough functionality to make it worth it.

Funny how neither Windows nor Mac has this ability as part of the OS. I would think it was something just about everybody wanted to do on a fairly regular basis. I am probably egocentric.

What exactly is it that you want to compare? The size of the folders? The contents?
