Delete Duplicate Files

Duplicate files are commonplace on Mac for a plethora of reasons. The users who are accustomed to managing multiple copies of their files soon find themselves in the trap of data redundancy and their system having a hard time running programs and other tasks. Duplicates may build up in your iPhoto, iTunes, iMovies and iWork library when you sync with any of your iOS devices on Mac.

You can create a duplicate of your current document for further reference or editing. This also contributes to piling up duplicate files on Mac hard drive.
