How to find duplicate files on Mac
Most Mac users have duplicate files, and often we have no idea how many duplicates there are on our computers. For example, if there is more than one user of a Mac, then the same music, images or documents could be stored twice, taking up valuable disk place. Let`s see how to find duplicates on Mac.
1. Find duplicate files on Mac manually
If you are trying to find duplicates on Mac manually, you may realize that it’s not that simple. You can sort files in the Finder by types (name, extension, size, etc.) and review all the files one after another. For that you would need to create a Smart Folder.
- Open Finder and use Command+Option+N shortcut.
- In a right top bottom click Plus button.
- Here you can choose the kind of files and folders you want.
- If you don’t see the criteria you need, click “Other…” and select the attribute for a search.
- Now open each file that has the same name or size and check for duplicates.
Well, as you see, searching for duplicates manually is not easy. The good news is that you can automatically find duplicate files with Duplicate File Finder. But before, let’s see how to find duplicate media files in iTunes library, which has a built-in function to find duplicate media files (music and video).
To find duplicate music and video files on macOS High Sierra or earlier, follow these steps:
- Open iTunes.
- Click the View in the Menu.
- Select Show Duplicate Items.
Since there is no iTunes on macOS Catalina, you should search for duplicates in Music and Apple TV separately. The steps are similar for both apps. For example, if you want to find duplicate music files in the Music app, complete the next steps:
- Open Music.
- Select Songs.
- Click the File in the Menu
- Select Library → Show Duplicate Items.
iTunes or Music will show you a list of duplicates. Examine the list and remove the duplicates. Unfortunately, to search for different types of duplicate files, you need to browse each folder in iTunes or open Music or Apple TV individually. That could take hours. But don’t panic! Now we will show the easiest way to find duplicates of any type of file with Duplicate File Finder.
2. Find duplicates with Duplicate File Finder
Duplicate File Finder is a great help when you need to get rid of duplicates on your Mac. The application will find all types of duplicate files on your Mac in less than a minute.
Follow these steps to quickly find duplicates files on your Mac:
- Launch Duplicate File Finder.
- Scan your Home folder for duplicates.
- Switch to the Duplicate Files tab. View your duplicate files and folders and remove unwanted copies.
- Switch to the Similar Photos tab. Select and remove unwanted similar photos.
It’s that easy! You can find duplicates of pictures, music, movies, documents, archives, folders and other duplicate files.
How to find hidden files on Mac
All Mac operating systems and apps create service folders and files that are hidden and necessary for normal system functioning. However, there are some hidden files that are not needed and just clutter the disk and consume space. All files that have a filename with a dot (or period) as the first character, are by default, hidden files.
If you want to hide some of your files or folders, just add a dot to the beginning of the filename.
But then, how do you find your invisible files and hidden cache files? The most common method is through the Terminal.
1. Show hidden files on Mac via Terminal
- Open the Terminal.
- Type defaults write com.apple.Finder AppleShowAllFiles true and press “Enter”.
- Restart Finder by the command killall Finder.
Now hidden files in Finder are visible. If you wish to make the files invisible again, type the same command, but change the word true to false. There is another command if you need to make a particular item visible again. Read more in our blog post on how to unhide a particular file or folder.
And here you can find the most useful commands for Terminal.

Finding hidden files is much easier and quicker with Funter, which is a free application. Funter allows you to view and hide hidden files with just one click on the Menu Bar. You can also hide or unhide individual files and folders via a shortcut menu or in the Finder window.
