Duplicate File Finder Pro is a macOS utility from Nektony that helps you find and remove duplicate files, folders, and similar photos to recover storage space.
What is Duplicate File Finder Pro?
Duplicate File Finder Pro is a Mac utility for finding duplicate files and organizing repeated content across folders, libraries, and external drives. It helps users recover disk space by scanning for duplicate documents, photos, music, videos, and other file types, then reviewing the results before removal. The app also supports finding duplicate folders and similar photos, which is useful when cleaning large media collections or consolidating files after backups and imports. Advanced cleanup workflows include tools for selecting duplicates to remove and merging folders with overlapping contents. It is designed for people who want a focused cleanup tool on macOS without manually comparing files one by one. Nektony offers it as a native desktop app for Mac.

Safety overview
Status: Mostly safe
This app’s file-scanning and cleanup purpose is consistent with requesting access to folders, Photos libraries, removable disks, and in some cases broader disk access so it can compare files across your Mac. Review scan results carefully before deleting anything, especially in synced folders such as iCloud Drive, Dropbox, or Google Drive, where removals can propagate to other devices. The product page identifies the app as Apple-notarized, which is a positive sign, but any duplicate cleaner can remove important files if used carelessly.
Recommendation: Keep it if you actively use it to clean duplicate files or manage large photo and document collections. If you no longer need duplicate-cleanup tools, you can remove it without affecting macOS, but check the final selection list before using it to delete files from shared or cloud-synced locations.
