Nektony has introduced Duplicates Finder 3.0.6 (https://nektony.com), an update of their freeware utility to find any duplicate file on Mac OS X. It’s a maintenance release.
The tool was specifically developed to help anyone find and delete all duplicate files en masse. Files are categorized by types for images, videos, music, archives, documents and all other specific extensions. Every found file is displayed in a corresponding category with its location on the hard drive, a quick link to the Finder, as well with file preview.
Duplicates Finder 3.0.6 is available worldwide through the Mac App Store in the Utilities category. It requires Mac OS X 10.9 or later.
