What is a GPD File Type?
You can modify a game by editing the associated GPD file, commonly Black Ops or Borderlands 2. This allows unlocking gameplay features that you didn't have before. To replace or inject a GPD file, move your profile from an Xbox 360 HDD to a USB flash drive and connect the drive to a computer running Windows with the Horizon or Modio modding tools installed:
Each game uses a unique title identifier to name its corresponding GPD file. The file name consists of a series of numbers and letters. You can open with a hexadecimal editor, such as HxD or HEXplorer, and change the hexadecimal code.
