I am syncing between a PC running WinXP and my PowerBook running OSX10.4.8 over my network at work. Can I do that with RsyncX? Will it update only the files that have had changes made to them and not re-copy files that haven't been changed? As an example: I'vegot 1gig of files that have previously been synced using RsyncX, 5 files totaling 6megs have been changed. When I run RsyncX again, will it re-copy the whole gig or just the 5 files?
