>Does anybody know of a good diff utility for .VCX files?

I used GKK compare from Downloads section here. BTW, when I tried to access it now from Home page, that link didn't work for me, so I can not give you the exact Download number.

UPDATE. I was able to access the Downloads section but I didn't find it there by searching for 'GKK'. I know Greg Green have the utility and I used it. May be he never put it in Downloads.
