You can manually find duplicate files on Mac but it’s time-consuming and requires too much effort on your side. We have a better solution for you. 

Find Duplicate Files on Mac

Using the smart folders trick on the Mac or a third-party app, one can easily find duplicate files on Mac. Read along to learn how to do it. 

1. Use Smart Folders on Mac

One of the common things about duplicate files is that they usually have a common name, or same date or common file type. Using the smart folders on Mac, one can quickly filter out such files and folders from the system.  You need to use the Finder menu for this. Follow the steps below to learn how. 

  1. Open the Finder menu from the Mac dock. 
  2. Select a location of choice to create a temporary Smart Folder. You can create a Smart folder on Desktop, Documents, Downloads, or any of the folders of your choice. 
  3. Click on File in the menu bar. 
  4. Select New Smart Folder from the following menu. Unfortunately, there is no keyboard shortcut for Smart Folders on Mac. 
  5. Click on the + sign at the upper right corner. 
  6. macOS will ask you to select the category type to sort out files and folders on Mac.  For example, if you know the name of files you are looking for, you can create a smart folder for them. Similarly, you can select Kind from the drop-down menu and sort out files based on file types such as music and videos.  Select the duplicate files that Smart Folder has identified based on your input and move them to trash.  As you can see from the steps above, this trick is most useful when you have an idea of the file type you are looking for. Also, there is no assurance of finding every possible duplicate file on Mac.  Besides, this is a tiring process and sometimes you might end up creating dozens of smart folders to remove duplicate files from Mac.  To simplify the whole situation, we have better suggestions for you. Using a third-party software like CleanMyMac and Duplicate File Finder Remover, one can easily find and remove duplicate files from Mac. Let’s talk about them.
