DWORD {4}    - Priority //priority that this tank is entered into the master index
DWORD {4}    - Flags //flags regarding this tank (eTankFlags)
char {4}     - CreatorId //"!GPG" who created this tank (creation tool will choose, not user)
GUID {36}    - //true GUID assigned at creation time
DWORD {4}    - IndexCRC32 //CRC-32 of just the index (not including the header)
DWORD {4}    - DataCRC32 //CRC-32 of just the data
SYSTEMTIME {16}   - UtcBuildTime //when this tank was constructed (stored in UTC)
WCHAR {200}  - Copyright Information ("Copyright (C) 1998-2004 Gas Powered Games. All rights reserved") (unicode text) (null terminated)

=== Extra - User Info ===
WCHAR {200}  - TitleText //title of this tank
WCHAR {100}  - AuthorText //who made this tank
//for GPG package, there're 24BYTE padding at here. But for user created package, there're nothing. byte {X}     - File Data


// INDEX 1 (Directories)

uint32 {4}   - Number Of Directories  in Total

// for each directory

uint32 {4}   - Offset to directory details (pointer into Index 2)

// INDEX 2 (Directories and Files)

// for each file or sub-directory

uint32 {4}    - Number Of Sub-Directories or Files

uint32 {4}    - Offset To Sub-Directory or File (relative to the Index 1, points to Index 2 or 4

uint32 {4}    - Offset To Parent Directory (relative to the Index 1)

uint32 {4}    - Number Of Files or Directory

FILETIME {8}  - Time Stamp

uint16 {2}    - Name Length

char {X}      - Name

byte {1-4}    - null Padding to a multiple of 4 bytes

byte {16}    - null Padding

// INDEX 3 (Files)

uint32 {4}   - Number Of Files  in Total

// for each directory

uint32 {4}   - Offset to file details (relative to Index 3, points to Index 4)

// INDEX 4 (Files)

// for each file

uint32 {4}   - Offset To Parent Directory (relative to Index 1 Offset)

uint32 {4}   - Decompressed Length

uint32 {4}   - File Offset (points to datarelative to dataOffset)

uint32 {4}   - CRC32

FILETIME {8} - Time Stamp 

uint32 {4}   - Compression Format (0 -> Not compressed, 1 -> Compressed ZLIB)

uint16 {2}   - Filename Length

char {X}     - Filename

byte {1-4}   - null Padding so each File Index is a multiple of 4 bytes

if (compressionTag == 1){

uint32 {4}   - Compressed Length

uint32 {4}   - Maximum Chunk Size (16384)

while (MoreDetailsMarker != 0){

uint32 {4}   - Decompressed Size Of Chunk

uint32 {4}   - Compressed Size Of Chunk [each chunk has a non-compressed 16 bytes added at the end]

uint32 {4}   - More Details Marker (0=no more comp data, 16=another comp data follows)

uint32 {4}   - Chunk Offset (points to datarelative to dataOffset)

}

Notes and Comments

• Compressed files use ZLib compression, broken up into separate ZLib chunks of size 16384 rather than compressing the whole file as a single chunk.

Supported Programs

• Game Extractor
