Newly installed C Cleaner and have noted that there are a very large number of duplicate files showing when I run the "Tools" and "File Finder" section.
Is there a method of deleting all of the duplicates rather than plough through the entire list one by one which I can see will be a very lengthy task?
Welcome to the forum Brian. I'm glad you had the sense to come here and ask about this feature before using it. I treat it as a "look but don't touch" item myself. If you look carefully, this size of most of these files is 10Mb or less, so at best, you'll only gain a few hundred megabytes of disk space. But if things go wrong, you could find yourself reinstalling Windows. The risks far outweigh the benefits in my opinion.
