I would like to clone some CD's because I've lost some expensive programs purchased on CD due to moving to a different address or damage to the original CD's. For instance, my two original Windows XP CD's (for two computers) were both cracked and rendered useless by the way there were removed from their sleeves and packed by a furniture removal company. It would also be nice to be able to clone DVD's. I have programs such as the Brittanica Encyclopedia on DVD. Which free or inexpensive program will clone CD's and DVD's in a simple operation? I have Nero but have removed it from my computer because the non-copying Nero programs, like the photo reader, aggressively interfere with my other software. Thanks for any good advice!
