Format Specifications

// DX Archive (v6) file format

// little endian

// Note: Whole archive is encrypted and compressed in most cases.
//       Custom key is required to parse data.

// header (48 bytes)
2 bytes (char) - signature  // "DX"
2 bytes (uint16) - version  // 6
4 bytes (uint32) - archive tail size (filename table + file table + directory table)
8 bytes (uint64) - data start address  // 48
8 bytes (uint64) - filename table start address (also tail start offset)
8 bytes (uint64) - file table start address  // relative to tail start
8 bytes (uint64) - directory table start address // relative to tail start
8 bytes (uint64) - code page // e.g. 1252

// data
num_of_files *
{
   x bytes - file data
}

// tail
{
   // filename table
   num_of_files *
   {
      2 bytes (uint16) - number of "packs"   // It can be calculated like this:
                                             // num_of_packs = (filename_length + 3) / 4
      2 bytes (uint16) - Parity?
      x bytes (char) - filename in uppercase + padding // e.g. "WHITE_BACK.JPG"
      x bytes (char) - filename + padding // e.g. "white_back.jpg"
   } 

   // file table (64 bytes per entry)
   // It contain headers for all files in archive
   // Note: There is one additional entry at the beginning (e.g. we have 32 files, but 33 entries)
   num_of_files+1 *
   {
       8 bytes (uint64) - filename offset  // relative to tail start
       8 bytes (uint64) - file attributes
       8 bytes (uint64) - file create time
       8 bytes (uint64) - file last acces time
       8 bytes (uint64) - file last write time
       8 bytes (uint64) - file data offset  // relative to header end?
       8 bytes (uint64) - file data size
       8 bytes (uint64) - file press data size
   }

   // directory table
   // Note: There is at least one entry in this table (for main dir)
   num_of_directories *
   {
      8 bytes (uint64) - directory offset // relative?
      8 bytes (uint64) - parent directory offset  // "-1" if there is no parent
      8 bytes (uint64) - number of files in directory
      8 bytes (uint64) - first file header offset for this dir  // relative to end of filename table
   }
