Help.. i need somebody, help.. not just anybody, help..... u know i need someone HELP !!

Ok, here's the deal, i have a DC with 18 original games (i know, i'm a retard), now i wanna make a copy of DOA2 for my friend, can't be done directly, so i downloaded some DOA2 files (i think) they have the following extensions.. *.001 *.002 etc. etc. What do i do with these files, can someone tell me please what 2 do?

Azz u might have seen i'm a newbie when it comes 2 burning DC stuff.. Very sorry if i have asked the wrong questions here, but please help me or set me straight..
