Duplicate File Finder

The tool scans a Mac’s storage to locate duplicate files, duplicate folders, and visually similar media such as photos and music. Users can select any disk, folder, or library—including Home, Photos, iTunes, iCloud, Dropbox, Google Drive, and external drives—to be examined, and can filter scans by file extension or size. Results are presented with preview options, allowing bulk selection through an “Auto Select” feature or manual choosing of items to keep or delete.

In addition to duplicate detection, the application can compare two specific folders byte‑for‑byte, merge folder contents, and move data between folders. It also identifies similar files, offering a view of near‑duplicate photos or songs so users can decide which versions to retain. Settings let users skip hidden files, customize selection rules, and confirm safe removal before deletion.

The software records removal history, supports restoring deleted items from the Trash, and provides a multilingual interface. It is distributed in free and pro versions, is Apple‑notarized, and has been downloaded millions of times.
