Pack

#PACK

PACK files are uncompressed files archives.

Format

PACK files are split into CHUNKs.

CHUNK

CHUNK blocks define a chunk of files within this PACK file. There can be multiple CHUNKs in a PACK file.

struct chunk_t
{
    unsigned int next_chunk_offset;
    unsigned int file_count;
    file_t* files;
};

next_chunk_offset defines the absolute offset to the beginning of the next CHUNK block. If the value is 0, then this is the last CHUNK in this file.

file_count defines the number of files contained in this block.

files is an array of file_ts of size chunk_t::file_count.

##FILE

struct file_t
{
    unsigned int name_length;
    char* name;
    unsigned int offset;
    unsigned int length;
    unsigned int crc32;
};

name_length defines the string length of file_t::name.

name defines the name of the file of length file_t::name_length.

offset defines the absolute file offset of the beginning of this file.

length defines the length in bytes of this file.

crc32 defines the result of performing a CRC-32 algorithm on all the bytes of this file.
