In short, do not delete any of them. Having looked through that list, although C.Cleaner has picked up on the fact that maybe two or three files have the same name at the front, the rest of the file shows each one is actually different and part of the first file or the program it is associated to. That is the same for every supposedly duplicated file, when in actual fact they are not duplicates at all.
Duplicate file finders are very suspect and it is only where you definitely recognise something, such as a photograph, music file, or other data is definitely the same file with a copy in a different folder. Wherever it says "Program files", you can bet it isn't really a duplicate and should be left alone.
I must also ask, that you do not use the registry cleaner part of C.Cleaner, you only need to look round the rest of the forum to see that not one of the technical staff or ordinary technical members such as myself, will ever tell you registry cleaners of any sort are any good, and in fact can lead to major registry damage.
Rest assured, we are quite often asked to help out someone who has done damage by using a registry cleaner.
