++/**
++ * Description
++ * There are two types of directory chunks -- index chunks, and listing chunks. The index chunk will be omitted
++ * if there is only one listing chunk. A listing chunk has the following format:
++ * 0000: char[4] 'PMGL'
++ * 0004: DWORD Length of free space and/or quickref area at end of directory chunk
++ * 0008: DWORD Always 0
++ * 000C: DWORD Chunk number of previous listing chunk when reading
++ * directory in sequence (-1 if this is the first listing chunk)
++ * 0010: DWORD Chunk number of next listing chunk when reading
++ * directory in sequence (-1 if this is the last listing chunk)
++ * 0014: Directory listing entries (to quickref area) Sorted by
++ * filename; the sort is case-insensitive
++ * The quickref area is written backwards from the end of the chunk. One quickref entry exists for every n entries
++ * in the file, where n is calculated as 1 + (1 << quickref density). So for density = 2, n = 5
++ * Chunklen-0002: WORD Number of entries in the chunk
++ * Chunklen-0004: WORD Offset of entry n from entry 0
++ * Chunklen-0008: WORD Offset of entry 2n from entry 0
++ * Chunklen-000C: WORD Offset of entry 3n from entry 0
++ * ...
++ * The format of a directory listing entry is as follows
++ * BYTE: length of name
++ * BYTEs: name (UTF-8 encoded)
++ * ENCINT: content section
++ * ENCINT: offset
++ * ENCINT: length
++ * The offset is from the beginning of the content section the file is in, after the section has been
++ * decompressed (if appropriate). The length also refers to length of the file in the section after decompression.
++ * There are two kinds of file represented in the directory: user data and format related files. The files which
++ * are format-related have names which begin with '::', the user data files have names which begin with "/".
