Clean Up Files

I am trying to get rid of duplicate files. I am finding these duplicates on 2 different HDDs and over 100,000 of them. I am not sure just how to safely remove what I don't use anymore and do it automatically with whatever software is recommended.

 

I have run various disk cleanup programs and none of them do the job. I don't know how the files got duplicated. My C;/drive which has my OS on it. The E:/Drive has a lot of software on it but I did notice it also has Windows and other duplicate files of C:/drive. I have used trial Clone File Checker to discover this but don't know what files to keep and what to delete.

 

Not that I am aware of. The last time, I had the CPU reparied the tech installed a few C:/Drive (500mb SSD) and the E:/Drive (HDD). I know he had to reinstall windows after the repair and I had to reinstall my softtware after that. Since my C:/ was the smaller of the 2, I decided to install my programs on the E:/Drive leaving the OS on C:/ along with other important files. I'm just going to take the time to view each drive side by side and remove what I see as a duplicate file, especially the windows folder on E:/Drive

 

I have seen horror stories about cleaning up thing like duplicate files and files I don't think that I need. Bricked the OS and had to start over. Lost a lot of important stuff from lack of backups.
