Header type is recognized by 3. ID: 'MPQ\x. 1A' means there's MPQ header at that offset'MPQ\x. B' means there's MPQ user data header at that offset. Both structures, written as C++ data types are here. MPQ user data. struct TMPQUser. Data. . The size of each logical sector in the archive is 5. Block. Size.

This table can fully replace hash table. Depending on MPQ size, the pair of HET& BET. Hash& Block table. HET table can be encrypted and compressed. The structure of the HET table, as stored in the MPQ, is the following. Common header, for both HET and BET tables. DWORD dw. Signature; // 'HET\x. A'. DWORD dw. Version; // Version. Seems to be always 1. DWORD dw. Data. Size; // Size of the contained table. DWORD dw. Table. Size; // Size of the entire hash table, including the header (in bytes). DWORD dw. Max. File.

The table of BET indexes is bit- based, and size of one entry doesn't have to be aligned to whole bytes. Using the BET index, get the BET hash from the BET table. If the values match, we found the file. If they don't, go back to step 5). Repeat until a HET hash of zero value is found, or until. Hash Table. Hash table is used for searching files by name. The file name is converted to two 3. The size of the hash table must always be a power of two. The structure of hash table is the following: // Hash entry. All files in the archive are searched by their hashes. This is a Windows LANGID data type, and uses the same values. Language versions are shown in this table: Value. Language version. Value.

More informations about hash theory are described. In World of Warcraft, the hash table was observed to be compressed in one of partial MPQs. Compressed size of hash table is calculated as: Compressed. Hash. Table. Size = (p. Mpq. Header- > dw. Block. Table. Pos - p. Mpq. Header- > dw. Hash. Table. Pos)Block Table.
