Each of my internal and external hard drives has a folder named $RECYCLE.BIN. I would expect CCleaner to empty these bins. But folders remain. Some are very old, and all have long names, starting with characters such as "S-1-5-18" I do not know for certain, but these may be old backup files from an application that I no longer use, having gone over to Macrium. Why do you suppose that Ccleaner does not delete these folders in the $RECYCLE.BINs in the several hard drives?
