In either case, cleaning up the copied files on your computer should help you out some. And don’t worry, we’ve done the hard part for you by ranking the top duplicate finder apps for your Mac.

1. Gemini 2

Topping this list is Gemini 2. Not only is it easy to use, but it’s also an intelligent duplicate file remover for Mac. After it scans either a specific folder or your entire hard drive, you’re given two options, reviewing the results or simply deleting the duplicates with just one click of the Smart Cleanup button.

If you decide you want to review the copies that Gemini 2 finds, you’ll see the obvious information like the filename and other metadata, and you can view the photos or playback videos and music files.

2. dupeGuru

Similar to some of the other apps on this list, when you scan your computer with dupeGuru, it not only shows you files with duplicate filename but it also checks your files to see if they’re similar in any way. It also has special modes for music and photos to look for and display different information for both file types. The one downside to dupeGuru is that its interface is a little older and may not be as straightforward as some of the other apps on this list.

3. Duplicate Sweeper

Duplicate File Finder Remover For Mac

You can scan any folder on your computer with Duplicate Sweeper, and it will show you all the copies of your files. Enabling the Auto Select feature will have the app choose which file you keep, but it’s strongly advised you still review those results before deleting any of them. Duplicate Sweeper scans everything in the folder(s) you select, including app files. So, if you accidentally delete a file that an app needs to run, then the app might not run correctly the next time you use it. Long story short, when using Duplicate Sweeper, just make sure you’re only deleting files you know are safe to remove.

4. Disk Drill

Disk Drill is actually a very powerful data recovery tool with an extra feature of duplicate finder for Mac. When you run Disk Drill, it will scan the folders you’ve selected and show you all of your copied files. The thing to keep in mind though, is that it will only show exact duplicates. Which means it might miss things like similar-looking photos where the angle is slightly different or duplicate files with different filenames. But one of the biggest benefits of running Disk Drill is if you do accidentally delete a file, you can run Disk Drill’s file recovery tool.

5. Easy Duplicate Finder


Easy Duplicate Finder delivers on everything its name promises. You can simply drag and drop the folders you want to scan. Like other Mac duplicate finders, it lets you quickly review and delete the copies that it finds. But it also has an undo-delete feature, so if you do accidentally remove a file, you’re able to undo it.

6. Duplicate Detective

Where Duplicate Detective really shines is with its simple-to-use and minimal interface. Even most novices would be able to open it and figure out how to find duplicate files on a Mac. But maybe you find yourself scanning for duplicates on a regular basis, the app has more advanced features, like Ignored Folder or Ignored File Extensions. So, you can scan better and smarter. If you download the trial to test it out, keep in mind, you can only scan for copied files, and if you want to delete those files, you’ll need to upgrade to the paid version.

7. Photos Duplicate Cleaner

Rounding out the list with a sleek interface is the app Photos Duplicate Cleaner. It scans your iPhoto or Photos library, looking not only for duplicates but also for similar-looking images. And it even works with libraries that are stored on external hard drives. The obvious downside is that this app is only for your pictures, so if you wanted to scan for copies of other file types in the future, you’d need another app.

But being consistent about scanning and checking for them will help you keep the number of them down. And not to mention, help your Mac run at its best.
