Zero Duplicates
Zero Duplicates is a macOS duplicate file finder that scans folders and drives to help you review and remove extra copies.
What is Zero Duplicates?
Zero Duplicates is a native macOS utility for finding duplicate files and freeing storage space. It helps Mac users scan selected folders or larger portions of a drive, group matching files together, and decide which copies to keep. The app focuses on duplicate cleanup across common file types such as documents, photos, videos, and audio files, which makes it useful for organizing personal files, project folders, and downloaded content. It also includes preview-oriented workflows so users can inspect matches before removing anything. For people managing cluttered storage, backup folders, or repeated imports, Zero Duplicates provides a focused cleanup tool rather than a general file manager. The app is published under the ZeroDuplicates name and distributed for Mac through Apple's App Store.

Safety overview
Status: Mostly safe
Zero Duplicates performs file scanning and deletion functions that are consistent with a duplicate finder for Mac. Because the app's purpose is to identify and remove extra copies, users should review duplicate groups carefully before confirming deletion, especially in project folders, synced storage, or backup locations where similarly named files may still be needed. Access to user-selected files and folders is expected for this kind of utility.
Recommendation: Keep Zero Duplicates if you actively use it to clean up storage or manage duplicate files on your Mac. If you no longer need duplicate-finding features, you can remove it without affecting macOS itself, but any in-app settings or saved scan data may be lost.
