How do you rip PC games?

I have a bunch of old PC games and It’s really cumbersome to have to locate the disks to play them. I was wondering if there was any way to rip the iso image from the game CD/DVD. I’ve heard of Game Jackal pro, but I would prefer a free option.
Thanks

install them….. an copy the installed folder to a backup cd or anywhere…… u can play them anytime….. thats how we play Counterstrike in the UNIV ^^
