How to Find and Remove Duplicate Files on Mac

It is hard to keep track of all the files on your Mac, especially if you are constantly downloading things. After using the computer for a while, you could have gotten a lot of duplicate files without even noticing. These files take up space and can even slow down your computer. It is necessary to find and delete them from time to time in order to speed up your Mac and make space for other new files.

Of course, you can use the most basic method by going through every folder manually, but this will take a tremendous amount of time. In this tutorial, we will show you a few alternative methods to find and delete the duplicate files on your Mac more effectively.

Delete Duplicates with One Click

Although Smart Folder can be very helpful, it still requires you to have a general picture of what kinds of duplicate files exist on your Mac. However, most of the time, we cannot remember the exact files that have been duplicated. If you want to find and delete duplicate files effectively, it is better to use a third-party app.
