Notes and Comments

• Files are compressed with ZLIB.
• The files in the archive are in a different order to the files in the directory. eg File 1 in the directory may be File 523 in the archive.
• Files are stored in sorted order of their original filenames, then in the directory entries are listed sorted by their file hash.
• Each file can have multiple compressed parts. Each part is described at each file offset. To determine how many parts there are in a file, go to the file offset and read the first field (firstPartOffset). Then do (firstPartOffset-fileOffset)/8 and you have the number of parts. (or you can just read the field in the directory!)
• Directory Entries which have NULLs after File Offset appear to be folders.
