Dup Detector

Dup Detector is a small but effective software that can help you locate and delete duplicate image files. The interface of the program is based on a standard window in which you can access a few tabs.

You can get started by pressing the "Build" button at "Primary data file" under "Get data", in order to browse for a folder to read images from. Optionally, you can include all subfolders (recursive search) and enable a quick count of files.

In the "View dups" area you can visualize any results (in two thumbnail images) and delete the one you want.

You can select the method (compare all images within the primary data file, compare images between two data files or compare a single image to the primary data file).

You can also configure duplication settings (e.g. duplicate within a specific interval for matches, set color or luminance match method, enable to check for mirrored images, set match restriction).

You can save a log file, select fast rebuild mode, change the viewing mode (e.g. large size dropdown view), configure folder preferences, run Windows Explorer, and more.

The software uses a low amount of system resources, includes a well-drawn help file (with snapshots) and didn't freeze, crash or pop up errors during our tests.

The fact of the matter is that Dup Detector is a very easy-to-use program for detecting duplicate pictures on your hard drive and we strongly recommend it.
