I don't know about GS/OS, but I know ProDOS keeps track of everything
in terms of blocks, and the fields for storing block numbers are all
16-bit integers, allowing only 65536 blocks, or 32768K, or 32MB maximum
for anything. Trying to increase the size of a block is only going to
send every existing Apple II program crashing down on us.

(In addition, ProDOS stores the size of a file in a 24-bit integer,
limiting the total size of a file to only 16MB.)
