What is Duplicate File Finder?
Duplicate File Finder is a Mac utility that helps you locate and remove duplicate files, duplicate folders, and similar photos so you can recover storage space and organize your data. It is designed for people who want to clean up crowded disks, review repeated media, or sort out copied files across folders and external drives. The app can scan common locations such as your home folder, Photos libraries, cloud storage folders, and attached disks, then group matching items for review before removal. It also includes tools for comparing or merging similar folders, which can be useful when consolidating scattered file collections. Duplicate File Finder is available for macOS and is published by Nektony.

Safety overview
Status: Mostly safe
This app’s file-access requests are consistent with its purpose because it needs permission to scan folders, Photos libraries, external drives, and other storage locations you choose. Use care when deleting results, since duplicate-cleaning tools can remove extra copies of documents, media, or library content if you select the wrong version to keep. If you rely on synced folders such as iCloud Drive, Dropbox, or Google Drive, review selections carefully so you do not remove files you still need across devices.
Recommendation: Keep Duplicate File Finder if you use it to free storage space or clean up repeated files on your Mac. If you no longer use duplicate-cleanup tools, you can remove it without affecting macOS itself, though you may lose its saved settings and any convenience it provides for scanning folders and libraries.
