OK, today i want to school and my friend gave me a cd that has 4.14 GB of files in it... I was freaked out... how the hell did he do that?!! He said he burned it on a speed of 4X... so now I came back home and tried it... but no use!! are there CDs that are dual layers or somthing like that? How do I burn files on a cd-r that are more than 700MB?
