I'm looking for a Windows GUI tool to compare the contents of two folders and show which files are different....

This question came from our site for professional system and network administrators.

Have you Googled? What are your requirements? –  Martijn Heemels Mar 1 '11 at 23:09
I'm not sure why this has 3 close votes already. It's the sort of thing I do often in my role as a system administrator. Incidentally, I prefer WinMerge. –  John Gardeniers Mar 2 '11 at 0:32
If you're comparing two files I'm sure it will be those two files that are different, if any. –  RichardTheKiwi Mar 2 '11 at 8:40
@cyberkiwi: hah, typo on my part... meant to say compare two folders. –  Brett Mar 2 '11 at 16:07

I use this WinMerge

SourceGear DiffMerge compares files and folders, and is free to use.

I'm a little bit shocked that Total Commanders folder compare ability wasn't mentioned so far.

Total Commander

Features in Total Commander 8.01 now include
- Two file windows side by side
- Multiple language and Unicode support
- Enhanced search function
- Compare files (now with editor) / synchronize directories

KDiff does a pretty neat job for merging. To add, it also allows Directory Comparison and Merge

Araxis Merge is by far the most popular and powerful, and the most expensive.
WinMerge is free, but is not very helpful when doing folder compare/merges/syncs.
Beyond Compare is a better option: has all the options (compare/merge/sync,) costs 360$ for 20 licenses.

Care to provide the source of your claim that Aaxis Merge is "by far the most popular and powerful"? I've never seen anything to suggest it's anything more than just another alternative. –  John Gardeniers Mar 2 '11 at 7:48

Another options is Beyond Compare or P4Merge

P4Merge is brilliant, my absolute favourite 3-way merge tool, but unfortunately it only compares individual files. It doesn't do folders, which is what the OP is about. –  Clafou Oct 9 '12 at 11:45
