It's just to big!!!
 

When I try to make a backup copy of Championship Manager 00/01 It always says that it is over 3000mb's how can this be and can I still copy it. I hope someone can help before my son break's it Blesshim.

let me guess your new at this. its not really 3000mb it has dummy files which are hidden. Tell windows to let you see hidden files (in the folder options). Once you can see hidden files look in the root of you cd rom drive probably d:\ you will see some very large files something like 600mb's each. Should copy perfectly with CloneCD.
