An Xbox 360 game disc typically holds between 4.7GB (DVD-5) and 8.5GB (DVD-9) of data. This data includes high-resolution textures, audio files (often uncompressed for quality), 3D models, and video cutscenes.
sometimes extract the game, compress assets individually, then repack. This is time-consuming and not standard for most users.
If you want help reducing storage use legally (compressing video captures, managing installs, choosing cloud/external drive), tell me which and I’ll provide steps.
