Breakdown

A_STRING	TOC file type header id " COT1000" (sequence: 0x20 0x43 0x4F 0x54, 0x31, 0x30, 0x30, 0x30)
UINT	Compression (?) - as of yet always 0
UINT	Items count
UINT	Items index size (should always be items count * 24; seemingly ordered by CRC)
UINT	Filenames size
UINT	Unknown (could be original filenames size, if compressed, as of yet always = filenames size)
UINT	TRE filenames count
UINT	TRE Filenames Size

<TRE Filenames count=TRE filenames count>

A_STRING

list of 0-terminated TRE filename strings, seemingly ordered by name

<TRE Filenames/>

<Item Index count=Items count>

USHORT	Compression flag (2 if compressed, otherwise 0)
USHORT	TRE index (in TRE filenames list)
UINT	CRC (of the filename)
UINT	Filename length
UINT	Offset in TRE file
UINT	Original item size
UINT	(Compressed) Item size, thus 0 if not compressed

<Item Index/>

<TRE Filenames count=TRE filenames count>

A_STRING

list of 0-terminated item filename strings, in the same order as the index items (by CRC)

<TRE Filenames/>
