.reg files in My Documents?

I've just noticed that my Documents folder contains 5 .reg files following a CCleaner run a couple of days ago. I've never had this happen before. Can someone please explain why they're there, and if it's a problem, how I should deal with it?

They are registry backup copies created by Crap Cleaner prior to registry cleaning. If you are sure you registry is fine and the pc is running fine too, you can delete them.

Thank you for your help.

just be aware @mdc124 that after a reg clean, your system can seem very normal, for ages, until the day you try to do xyz and realise something is amiss.

and the time gap can be so great that you never join the dots back to a reg clean as the likely culprit.

I'm just keeping the .reg files. Just wanted to be sure they weren't malware.
