I fear you have answered your own question. It looks like there is a 2 GiB limit somewhere... maybe not a limit of NSFileWrapper but of one of those private classes like NSAKSerializer. I recently learned the hard way that NSKeyedArchiver is also limited to 2 GiB. Cheers, -- ____________________________________________________________ Sean McBride, B.
