I tried the duplicate file function in CCleaner, it works well, but has one MAJOR drawback that severely limits its usefulness. There is no way to compare two folders on two different hard drives. For example if I want to compare the "Music" folder on C drive with the "Music" folder on F drive there is no way to do it. Only option I get is to compare ALL folders on C drive with all folders on any other drive OR at best ALL C drive folders with the selected folder on the other drive. There is no way to compare files and find duplicates in any single folder on one drive with another. It would make it much easier and much less time consuming to scan only the folders you want to compare, instead of doin the entire hard drive each time you run the program.
