You might wish. Except in some very old VAX environments (where
off_t, or size_t, or whatever it used, is unsigned), the limit is 2GB.

Version 2.32 is the current released version, and solves several
problems (VMS-specific and general) found in earlier versions. I would
not touch Zip 2.3 with a sharp stick, if I could get hold of anything
newer.
As a quick Google search would reveal, Zip 3.0 and UnZip 6.00 will
offer large-file support. Old but usable "BETA" source kits should be
available at:
ftp://ftp.info-zip.org/pub/infozip/beta
Try to ignore any warnings from UnZip 6.00c which mention "76 bytes".

Depending on where you got that program, and how it was built, it may
or may not do much better with large files.
