The PathTable Sector isn't complicated when there are no files on the CD!

Don't forget that this file will be %includeed twice: once with ISO.Endian %defined as Little, and then again as Big.

; This file defines the ISO Path Table. There are two similar flavours: Big and
; Little Endian. To that end, this file expects the ISO.Endian macro to be set
; to either Little or Big before being %included.
