For a long time, I didn’t know a way to do directory comparison using git difftool command, extdiff extension from Mercurial did perform much more superior than Git. Though it may be a bit out of date, I just found that after v1.7.11, Git now supports directory comparison through --dir-diff option, fantastic! UPDATE 12/11/2012: You will need v1.8.0 version of msysgit installed, as noted by Scooter Software (Reference). So here is a list of steps for me to make Beyond Compare 3 and Git directory comparison work under Windows.
