The file type word of entry 11, and of the ProDOS form of entry 7, holds the codes below. ProDOS 8 uses only the low byte of the word; GS/OS and ProDOS 16 use all of it. The three-letter names are the ones Apple’s tools show. Codes not in this table have no assigned type, and the auxiliary type’s meaning depends on the file type.
