Rating: 4.0

Ashisoft Duplicate File Finder can compare files byte by byte, so it can find true duplicate files regardless of filename. It has a free edition and a pro edition. Both allow you to look for various types of duplicates such as duplicate music files, pictures and videos.

The interface is simple and easy to understand even for new users. It displays options and actions for users to take. You can choose to identify duplicates by byte-by-byte comparison, the SHA-1 algorithm or file properties. It provides multiple search filters, duplicates marking options and removal options. You can also exclude folders for scanning, which is a safety feature to prevent accidental delete. Its ability to find duplicate music files is also worth mentioning. This duplicate file finder for Windows 10 (and other versions) can measure and identify similarities between songs by content or by ID tags like title, album and artist. If you choose to find duplicate music by content, the app will ignore these tags and only focus on file content.

The free version only provides basic features and options, which may be enough in many cases. To have access to advanced features (such as support for Google Drives), you need to upgrade to the pro edition. Its ability to find duplicate files is slightly lower than that of some similar tools such as Auslogics Duplicate File Finder.

This free app can find the duplicate photos in a Mac folder. However, it can't find all of them. It works extremely slowly when scanning a large folder or drive for duplicates. And, a preview feature, which is essential, is missing.

The scan results will be displayed with thumbnails. You can preview them with the built-in preview feature. Go through the results and select the unwanted duplicates for deletion.

Dedicated to handling images, this free duplicate photo finder can work with both Photos libraries and the regular folders. When scanning Photos library, it will ask you to quit Photos app first if Photos is running.

In the test, it couldn't find all the duplicates. Some exact duplicates were missed. Also, sometimes a scan may fail, and you need to perform a scan again and again until it works properly.

It's indeed an awesome app to search for photo duplicates and image duplicates. The process is easy. The speed is not bad at all. It can even identify slightly edited versions of the same photo, helping you easily locate the best version to keep.

The preview feature is useful, letting you conveniently preview and compare groups of duplicates found on your computer.

In each group, manually delete the duplicate that you don't need anymore. However, it will take hours or longer if there are a lot of duplicates. You have to be very patient.

Araxis Find Duplicate Files (Mac)

Provided by: Araxis Ltd

Compatibility: macOS 10.6 or later

Latest version: 2013.433, released on February 2013

Note that the app is discontinued. It may have compatibility issues with newer macOS versions.

Supporting various types of files such as images, archives, music files and documents, it can detect most of the duplicate images and other duplicates in a folder on Mac.

However, it's not designed to scan Photos Library for duplicates. If you are looking for a good Apple Photos duplicate finder, ignore this app.

An Apple Photos duplicate finder should only check the actual photos in your library in order to identify duplicates and shouldn't touch any other data in the library. But Araxis Find Duplicate Files will check both the photos and the data. Removing the found duplicates as the app suggests will damage your library.

Cons

1. Can't find all duplicates
2. May damage your Photos library
3. Not well compatible with new macOS versions
4. Crash when scanning a large amount of photos
5. Discontinued

CCleaner Free (Windows & Mac)

The free edition of CCleaner can be used as a free duplicate photo finder and deleter due to its built-in Duplicate Finder tool.

The tool can find duplicate copies of images, videos, audios and most other files. CCleaner Free for Windows allows users to search a specific folder for dupes. But if you are a Mac user, you won't be able to specify a folder.

For Mac users, there are only two options: Search entire disk and Search only user folders. With both options, the search will take hours and even days.

It's recommended to preview duplicates before deleting them. But there isn't a preview feature. To take a closer look at a duplicate, you need to open the folder containing it, which is not convenient.

Pros

1. Available for Windows and macOS
2. Search for duplicate pictures and other duplicate files

Cons

1. Almost useless macOS version
2. No preview
3. Don't search for subfolders for duplicates by default
4. Can't find all duplicates

Duplicates Finder (Mac)

Provided by: WinZip Computing LLC

Compatibility: macOS 10.7 or later

Latest version: 1.0.0, released on 12 Apr 2016

This freeware app can scan both folders and Photos Library for duplicates. However, it may damage your Photos Library, just like Araxis Find Duplicate Files would do.

The app is capable of identifying most of the duplicate photos in a folder on your Mac. The duplicates will be listed in the results window in groups. You have to manually select the unwanted duplicates one by one and then click the Remove Selected button to get rid of them. There is no way to do it automatically.

Cons

1. May harm your Mac Photos library
2. Can't find all dupes
3. Can't deal with a big photo collection
4. Have to manually select duplicates to delete one by one
5. Display no preview at all

Summary

There aren't many truly free duplicate photo finders available for MacBook Air, MacBook Pro, iMac, Windows PC, etc. I have tested the ones that I can get my hands on.

As you can see, they may have some features that you expect from duplicate photo finder software, such as automatically identifying duplicates. But they are not good at it.

What's more, for Mac users, all the free apps can't deal with the Apple Photos app for Mac. To make matters worse, they may damage Photos Library.

Some of the free duplicate photo finders may crash, and some of them are pretty slow. You may spend much time trying these apps but end up still having the duplicate photos on your hard drive.
