A standard PS2 game DVD holds roughly 4.7 GB of data. High compressed versions are shrunk down significantly—often to sizes ranging from 100 MB to 1 GB—using advanced compression formats like .cso, .zip, or .rar.

When a game is compressed, empty data (dummy files) is removed, and the remaining data is packed tightly. This results in a much smaller file that is faster to download and easier to store on your hard drive or Android device.
