  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.
