Info updated on:

Duplicate File Doctor is designed to help you identify and remove duplicate files from your hard drive. Therefore, you will retrieve valuable disk space and improve your system's performance. With a clean computer, the running operations will complete in a shorter amount of time and without unexpected errors.

The program opens with a simple, yet rather dull interface. However, you have the advantage to find all the provided functions conveniently placed on the main window, so you won't need to look for hidden settings and preferences. You have the ability to select one folder at a time or multiple folders at once to be scanned for duplicate items. If you added a folder into the list panel accidentally, you can remove it easily with just a click of a button. The tool allows you to narrow your search for duplicates by size and extension. Thus, you are provided with two easily manageable sliders that will let you determine the minimum and maximum file size interval to be taken into account during the scan operation. In addition, you can narrow the search even more by asking the program to look for duplicates within specified file extensions. Unfortunately, file category filters aren't supported, although they may be more appreciated by common users than the file extension criterion.

Once the scan operation is completed, a new window is displayed, giving you the chance to browse for those duplicate files that are worth deleting. The app doesn't come with a preview of the identified items, yet it offers the ability to open them in Finder from within the program. The selected duplicates will be moved to Trash or removed permanently, as you prefer.

In short, Duplicate File Doctor offers a simple solution to regain wasted storage space by deleting unnecessary duplicate files. A good thing about this program is that the scan settings can be saved as standalone profiles to be used on other occasions. The real-time notification about the disk space you are about to save if you delete the selected files is also a great asset.
