Chunks
The Chunks file format is used for (almost?) all binary type files. It basicly is a container type to pack different binary files together.
The format is very simple, the Chunk Header consists of a file type identifier as ascii string, padded with junk to fill full 16 bytes. Then comes a 4 byte/32bit (unsigned?) integer indicating the size of the chunk, excluding the header.
Format Structure
Chunk Header
| Bytes | Use |
|---|---|
| 16 | chunk type identification + padding |
| 4 | size of chunk (excluding this header) |

Notes
A lot of information about those file formats is known, because of Sir Henry/wzurborg’s code releases. In particular the two files Anno1602read.h and Anno1602read.c which seem to be original code excerpts (??).
