How does it compress it that much?
Effective compression ratio depends heavily on the data being compressed. To achieved a 98% compression ratio you have to be compressing a file that is either empty, or breaks down into simple patterns. Usually, stuff like office documents will be like this.
Executable data doesn't compress nearly as well, while most media such as music, video, and game objects are already stored compressed by the media provider and are decompressed on the fly when the game is running in order to economize available storage bandwidth.
So really, I am surprised you were able to get it to compress half a gigabyte out of it. Because the bulk of the data being compressed by 7zip would already be compressed by another algorithm, and would not get a very good compression ratio when compressing further.
