Duplicate Detector

Duplicate Detector is a smart Windows software that makes it easy to find and remove duplicate pictures and videos from your mass-downloaded media folders. Simply drag in one or more folders, even ones packed with subfolders, and the program scans everything and fingerprints every file. It catches exact copies that are byte-for-byte identical, and it also catches visual duplicates such as the same picture resized, recompressed, or lightly edited, where the files differ, but the image clearly looks the same. Matches are lined up side by side in clean groups with a similarity score on each one, along with the file name, resolution, size, and date, so you can see at a glance which copy is worth keeping. A sensitivity slider lets you decide how strict the matching is and regroups your results instantly. Duplicate Detector suggests the best copy to keep in every group while you stay in full control, then clears out the rest in a single click, handing you back a clean, clutter-free library in minutes. You can also just run the auto detector and let Duplicate Detector automatically clean up your folders, saving the files with the best quality
