Is there a maximum number of recipients (public keys) a file can be encrypted for when using PGP zip?
I know that theres a limit of 120 users for pgp desktop WDE, so that is a good figure to use as a guide, but I don't think there is a figure quoted in any of the manuals.
I'm not aware of a limit, and can't find anything suggesting a limit. At extremely high numbers, it may possibly depend on your hardware.
