MOD File Format
This is a description of the MOD file format used in Neverwinter Nights.
The first thing in the file is the Header block.

| MOD Header |

| char[4] | Signature "MOD " |
| char[4] | Version "V1.0" |
| dword | Unknown |
| dword | DescriptionBlockSize |
| dword | NumberOfFiles |
| dword | DescriptionBlockOffset |
| dword | FileHeaderTableOffset |
| dword | LookupTableOffset |
| dword | Unknown |
| dword | Unknown |
| dword | Termination (-1) |
| DescriptionBlock |

| dword | 0 |
| dword | TextLen |
| char[TextLen] | Description |
The FileHeaderTable is a list of FileHeaders. NumberOfFiles above
dictates how many of these there are.
| FileHeader |
|---|
| char[16] | Filename |
| dword | Index |
| dword | FileType |
The filename is a unique identifier for the file. Here is a list of all known filetypes. The Index
is the index into the LookupTable.
The LookupTable is a list of offsets and sizes for each file.
The offset points to the beginning of the file data.
| LookupTable |
|---|
| dword | Offset |
| dword | Size |
I've written a quick example that'll parse a MOD file, and dump
the main module.ifo file. DumpMOD.C
