How do I copy a 2.91gb Game!

[paul777]

Hi this may seem a dumb question to most of you, but here goes I was trying to make a backup copy on the PS.2 game Tony Hawks Pro skater3. I put the original in my p.c. drive to copy. properties said it was 2.91 gb.. how is it posible to copy when most blank media is in the range of 700mb-900mb! can this be done or is there larger blank media I don't know about
Thanks Paul.
