So, last time I checked:

iFolder 2.1, that is:

It didn't really do a delta sync, since most applications (Office, etc.)
actually delete the original file and save a new file (same name) when
you make changes.

Rumor had it that Novell was working on some method to do a CRC or
something so that if the file name was the same, it could sync ONLY the
changes. Maybe ala Rsync or something?

Is this "fixed" in iFolder 3.x?

Or, if you open a Word document, change one letter, save it again, does
iFolder sync the entire file all over again, still?
