ISO = Direct Image copy of the UMD disc.
CSO = Compressed version of an ISO.

CSO's save space but can render a game unplayable if compressed to much. If you have a CSO that wont play, try it at different compression levels. You may find the only way to play a certain game is by ISO only.

that kind of file should be a .rar

make sure its set to open with WinRAR in the file properties. also make sure you have WinRAR downloaded on your computer.

ya then it may be the actual ISO broken into several pieces. You'd need a third party program to piece it back together.
