Gemini 2 is a popular application designed to search for duplicate files, duplicate folders and similar photos. The application supports external drives, Photos and iTunes libraries, helping to get rid of unnecessary copies of songs, series of failed frames, duplicate photos and other types of files.
Its developers say that Gemini 2 uses intelligent algorithms and improves its search criteria for each type of duplicate, depending on user behavior. Also, the developers introduced gamification in the app, making the cleaning process more fun for the users.
The main screen of the application consists of one “+” button. So all you need is to add or drop the folder you want to scan. Then push the green button to start scanning. Once the scan is completed, you will see a short piece of information about the volume of duplicates on your Mac.
Click Review Results to see the list of exact duplicates and similar files that Gemini found. The app provides two modes for this screen. You can preview the results as icons or in a list. Files are divided into categories – music, videos, documents, images, folders.
Please note that the application automatically selects duplicates on this screen. You can preview them in the Selected section. Just be careful to not delete important files, especially since duplicates detected by the app may include similarly-named files or almost identical files but with imperceptible modifications.
Gemini software finds not only duplicate photos but also similar images. For example, if you have several photographs showing the same object but taken from different angles, Gemini will display them and suggest leaving only one. You will find such files in the Similar Files section. Double-click on each file to preview them in the comparison mode.
With the Gemini app, you can make your photo albums more accurate, freeing them from a series of identical pictures. MacPaw Gemini will also be appreciated by music lovers whose iTunes library lacks orderliness.

Duplicate File Finder from Nektony quickly and efficiently finds duplicate files, duplicate folders, similar folders, and similar images. It provides an opportunity to search for duplicates not only on the hard drive but also on the local network. It can work with images, music, videos, archives and any other type of file.
Duplicate File Finder has a clean design and large number of useful features. Once you drag and drop your folders to the start window, click to scan them.
The application will check all the files in the folder and show you a brief summary of duplicate content on your Mac. The report is presented in two types: a bar chart and a pie chart.
The sections of the diagram are active; click on them to switch to the appropriate tab of duplicate files or folders.
If you often take the same picture from a dozen slightly different angles and import all of them to your Mac, then Duplicate File Finder will successfully help you to bring order to 100+ photos.
The application also finds similar photos and allows to remove unnecessary ones.
In the Similar Photos section, you can find all similar pictures and compare them in a convenient Preview section, deciding which ones you want to remove.
The intuitive Auto Select option will help you save time and automatically remove the newest or oldest ones.
Now let’s take a look at the unique features of Duplicate File Finder, which no other application has: the Similar Folders and Merge Folders options.
Besides duplicate folders, the Nektony application finds similar folders- folders with both identical and unique files.
You can select duplicates in these folders with just one click. The program will retain all unique files. The best thing that the application allows you to do is to merge similar folders. Merging folders allows you to get rid of an infinite number of similar folders, and organize files in the process.
And that’s not all. When it comes to providing the best experience in removing duplicates on the Mac operating system, Nektony can’t be beat.
With the help of the “Select Duplicates In Folder” option, you can configure the folders in which the app will automatically select duplicates. Ticking the checkboxes next to the folders will prompt the app to select duplicates in them. Marking the folders with the star icon will protect your folders from the accidental removal of duplicate files.
After selecting duplicates, click on the “Review & Remove” button. A list of files selected for deletion will be displayed and you will need to confirm removal.
Depending on your preference, duplicates will be sent to the Trash, moved to another folder, or removed immediately. All these options can be set up in the app’s preferences.
