Start	Stop	Size	Type	Name
0	3	4	UInt-32	Name Offset
4	7	4	UInt-32	Storage Flag
8	11	4	UInt-32	Relative Data Offset
12	15	4	UInt-32	Compressed Size
16	19	4	UInt-32	Decompressed Size

File Definition (Impossible Creatures)

Start	Stop	Size	Type	Name
0	3	4	UInt-32	Name Offset
4	4	1	UInt-8	Storage Flag

Storage Flag
