That ExamDiff looks good but it says that you need the pro version to highlight file differences down to the level of words or characters in changed lines and it does not do word wrap for long lines. These I think are needed features that make it kind of useless without them since sometimes a file won't work because it is missing a comma or a word has upper or lower case difference.
There is a file compare utility that comes with NSW2003 but it only works with Win9X OSes. I hope it comes with NSW2004 but that remains to be seen.
I would love to have a decent freeware file compare utility too so I hope someone adds one to this thread. I haven't found one yet.
