Storing your back-ups on ur hard-drive consumes huge amount of space. Just recived an email for an anonymous source with this image. They would like to know; How someone has compressed a 1.45gb file into a 33.2mb compression?
It depends on the game. All games as a raw image are the same size, but much of the time the garbage data can be highly compressed. Just because the disc is 1.35GB doesn't mean the game itself uses up that much space. Some games, like Pikmin or or Ikaruga, are easily compressed to fractions of the original size.
I'm also wondering how this is done because I notice a lot of the newer scene releases are much more compressed than the older ones. Maybe the new winrar has a feature?.
