Notes and Comments

  • Files are ZLib compressed?
  • 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.
  • 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!)
