I tried to search, but kept getting answers for malware and infections. What I am looking for is simple. I very likely have some files on my hard drive, and the same files on another location of the drive. I know if I try to move a file into a folder that already has that file, or file with that name, it will warn me and allow me to compare the files by size. Is there a program there that allows me to find all my potential dupes, so that I may evaluate and delete the extras, clearing some space. If not already in windows, can someone maybe point me to a reliable free program that will allow me all that, but won't infect me with anything either. Thanks.
