Notes and Comments

• The first 3 directories probably always exist in each archive, and contain the same number of files in each of these 3 directories. The other directories appear to be optional, and contain random numbers of files. The file ID's in each HASH directory always go between 0 and numFilesInDir-1, but they are not in order. Also, the Hash values in the HASH directories are non the same in each HASH directory, so they may be calculated on different data if they are a Hash.
