Best utlities for file and directory compare and merge?

[Guest xts44]

What are the best utlities for file and directory compare and merge? I've been looking for a bit and haven't found one I liked yet.

1. This should be in the Software forum.

2. It would help if you mentioned what you've tried so people don't waste time telling you about programs you're already familiar with.

I use a freeware prog called WinMerge on to keep my portable drive synced with both a folder at home and one at work. Could be a bit painful if you had too much stuff to compare though.
