How to Grant Access to Folders on macOS Catalina

Duplicate File Finder is a software tool that finds and removes unneeded duplicate files, folders and similar photos from your Mac.

Starting with MacOS 10.14, Mojave, Apple has implemented a new security feature that requires some applications to be permitted to work with your data. This means that now you have to manually grant access to your apps to let them work with the user`s files.

These changes also affected the way Duplicate File Finder works.
In this article, we will show you how to allow Duplicate File Finder to scan all the necessary locations on your device, in order to find unneeded duplicates.
