Why you have duplicate files?
The duplicate files may generated by repeat downloading from Internet/emails/internal network, copying, backing up, forgetting someone and getting it again, etc.
Why need software to find duplicate Files on hard drive?
First: the duplicate files waste your disk space, especially, movies, software installers and music videos.

Second, and more important: they will increase your maintenance costs. For instance: when you need to use a file, and you found there are several similar or exact same copies in your PC, you may open all of them one by one to decide which is you need, because you cannot determine whether they are exact duplicate by a glance. If you want to open a Word document, and it has 600 pages, and there are 6 similar or exact same copies, it would be a nightmare to find out your need.

Third: just like some people like cleanliness, they do NOT allow the unnecessary files exist on their computers.

For these reasons, I think you should need a program to find duplicate files.
