I might add one additional caveat: In AIX 4.2 they started supporting
Large File Systems (greater than 2 Gig).
If your file is greater than 2 Gig, then your filesystem will need to be
Large Enabled. AFAIK, there is no
Conversion, you have to create a new jfs that is large file enabled. We
have used them for years.

As someone else pointed out, watch out for the standard Unix utilities
that do not support files > 2G.
