I'm running the latest version of CCleaner (5.17.5590) on Windows 10 Professional (32-bit version) and try as I might (multiple times) I cannot get the Duplicate File Finder Tool to function on my Western Digital 3TB NAS backup drive. The tool will recognize the drive and allow me to set the path statement to it (\\Drive-Z\Public\*.*) but when I execute it, it "runs" instantly without ever searching the drive and finding any files. I've even gone so far as to actually install it on the backup drive itself but it will simply not go out and find any duplicate files on it. I really need this to work because I've got hundreds of duplicate files on my backup drive which are taking up many megabytes of space that I need to recover. It works perfectly on the C: & D: drives on my computer and even recognizes the "phantom" USB memory card slots, but not my Z: drive. If somebody could just tell me how to get CCleaner to on my backup drive I would be very appreciative. By the way, I don't need any other feature of CCleaner to run on the NAS drive, just the Duplicate File Finder.
