What cloned files should I not delete?

I am using Advanced System Care and I have zillions of cloned files. But I don't know if I should delete all of them. Is there solid reasons why I should keep them? Some of these are cloned 5+ times. I run on windows 7(64bit) and I know there is compatibility programed into for 32bit and 98 vs XP vs Vista.


So I am wondering if I am seeing some sort of product of that or if it is something I don't understand. Just trying to get some clarity here.

 

I am in the same quandry. Same softwear also. It finds the cloned stuff then gives and extensive warning about how some of them may be useful/necessary. So then what? NORMAL people like me are then dazed and confused.

So what should we do...riddle me that geeks.

 

Do nothing unless you understand what you are doing and any possible side-effects or are prepared to wipe/reinstall Windows.
