CHD is a lossless compression format. It significantly reduces file sizes without any loss in game data or audio quality, making it a highly recommended compression type for disc-based systems. Single File Management:

This single-file structure is robust. It is easier to hash, easier to verify, and easier to store. It ensures that 50 years from now, if someone wants to play Panzer Dragoon Saga or Radiant Silvergun , the file they find will be self-contained and identical to the original disc.
