The limits for resource forks are the same as for data forks
Not true - the ResourceMap contains some 24-bit pointers, or at
least it used to, as well as some 16-bit length fields as well.
Unless these have been changed (possible I guess, I don't know)
these will bite you before the file fork limitations do.
I was imprecise in my original statement. I meant what Graham says:
The resource FILE format has some limits (offsets and things it uses
are 24- and 16-bit quantities, as Graham said. Of course, the resource
FORK itself can grow as much as it wants. But that won't help you
much, since applications like the Finder expect the resource FORK to
contain a valid resource FILE so they can add their own 'usro'
resources and such that indicate what app to open a file with. So, for
all practical purposes resource FORKS are limited by the format of the
resource FILE.
