What is an MPQE file?
Encrypted Mo'PaQ (.MPQ) file used by some Blizzard games, such as Diablo 3 and StarCraft 2: Heart of the Swarm (HOTS); saves game data but encrypts it so that it can only be decrypted with a beta key or other game key; keeps unauthorized users from playing the game.
Since MPQE files contain large amounts of game data, they can be gigabytes in size.
