What is Duplicate Finder and Cleaner?
Duplicate Finder and Cleaner is a native macOS utility for finding duplicate and similar files across photos, videos, music, documents, applications, archives, and other folders. It is designed for Mac users who want to reclaim disk space and reduce clutter without manually comparing large collections of files. The app supports scanning regular folders, external drives, multiple Photos libraries, and iPhone backup locations stored on a Mac. It presents results in grouped views so users can review matching items before deciding what to keep. It also includes automatic marking tools to help preserve one preferred copy in each duplicate group and offers removal options such as moving items to Trash, deleting them, or moving them to another folder. Moneyplant Technologies distributes the app for macOS through the Mac App Store.

Safety overview
Status: Mostly safe
This is a legitimate Mac App Store utility for duplicate-file cleanup, and its file access is consistent with its purpose because it needs permission to scan locations you choose. Use extra care with any permanent-delete option, since removing the wrong copy can affect personal files, photo libraries, or backups. If you use it, review duplicate groups before confirming removal and prefer moving items to Trash first.
Recommendation: Keep Duplicate Finder and Cleaner if you actively use it to manage storage or clean large file collections. If you no longer use it, removing the app is reasonable; just make sure you do not delete files you intentionally kept elsewhere while cleaning duplicates.
