Duplicate Manager Pro
Duplicate Manager Pro is a macOS utility for finding duplicate and large files so you can review them and free up storage space.
What is Duplicate Manager Pro?
Duplicate Manager Pro is a macOS utility that helps you find duplicate files and large files across folders, external drives, network volumes, and other storage locations you can access in Finder. It is designed for people who want to clean up photo libraries, video folders, music collections, document archives, and mixed file storage without sorting everything by hand. The app includes preconfigured scan jobs, manual folder selection, exclusion options, and several comparison modes for different duplicate-finding workflows. It can auto-select duplicate groups based on rules you choose, set folder priority so one location keeps the original, and optionally move removed items to the Trash. Duplicate Manager Pro also supports scheduled scans, which can help users revisit recurring cleanup tasks over time. Greenworldsoft offers it as a focused file-management tool for Mac users who want a dedicated duplicate finder rather than a general storage dashboard.

Safety overview
Status: Mostly safe
Duplicate Manager Pro is a file-management app, so access to user-selected folders is consistent with its purpose. Its core risk is operational rather than malicious: deleting duplicates, using auto-selection, or relying on looser comparison modes can remove files you intended to keep. The app's own guidance distinguishes checksum-based modes from less strict matching methods, so review matches carefully before removal and prefer moving items to the Trash instead of immediate deletion.
Recommendation: Keep Duplicate Manager Pro if you use it to clean up duplicate or oversized files on your Mac. If you no longer run duplicate scans, removing the app should only take away that cleanup workflow. Before deleting anything from scan results, review the kept-original rules and confirm important folders are not being cleaned automatically in a way you do not want.
