📢 New (Windows, Linux, & MacOS) Release: Downloads 🔥

Media-File-Duplicate-Finder finds duplicated video and image files based on similarities. Finds duplicates which have different file types, format, resolution, frame rate, watermark, and file tags.

MediaFileDuplicateFinder (MFDF) was originally a fork of 0x90d/videoduplicatefinder. Originally this fork was created so-as to add more features and to give the UI a more standard intuitive interface. MediaFileDuplicateFinder has fully broken off from the original fork, so that users can report issues and post enhancement request directly.
