A is a curated collection of these compressed game files. By using lossless compression, CSO files reduce the footprint of a game by up to 60% without sacrificing gameplay quality.

The "cso psp archive" keyword will lead to numerous websites, but not all sources are legal or safe. Here are legitimate ways to build a CSO collection:
