Notes and Comments

Note 1 - The ID/Type tag for the file contents. Where 0x01000000 indicates a regular file, and 0x02000000 indicates a texture (*.DDS, *.PNG, *.TGA and *.BMP). In case of a texture 4 additional uint32 values are stored after the the filename and before the archived file contents. The texture files are archived without a header, the 4 additional uint32 values can be used to reconstruct it.
