Most computer users create and download different files on a daily basis. As time goes by, hard disks get packed with documents, pictures, music, videos, and other files. And then suddenly there is almost no free disk space left! But that is only partly true. Most people are unaware of how many duplicate files there are cluttering their hard disks. All those songs that have been downloaded twice, holiday photos uploaded multiple times, documents copied and pasted, so that you have them in two folders at once. All that wasted disk space can be reclaimed by simply deleting duplicate files.
