Dup Detector helps you to detect quickly duplicate images in your image collections. By using a powerful algorithm, it can display duplicate images even if they do not have the same name.
The process is simple because you just specify the path to begin digitalization. This program can give you the percentage of duplicated images and a visual preview so that you can delete the junk file. It can process 9 images at once from a folder, from a sub-folder or from a list regardless of the file size. This software is entirely free and has hot keys.
