Duplicate File Finder got a new update, and the latest version has a totally new design and the features you were asking for.

Duplicate File Finder is an application that finds all types of duplicate files and similar photos. After adding a feature to merge similar folders, our support team began getting messages from the users asking us to add a feature to merge any folders on a Mac. Since our users’ feedback always inspires us to make the application better and even more useful, we started working on this task. However, besides providing a new feature, we updated the design, making it more user-friendly.

Before showing you how the new feature is working, let us explain what are the benefits of Duplicate File Finder.

  • Find duplicate pictures – scan even Photos Library for duplicates.
  • Find duplicate music – find duplicate and similar audio files in any folder, including Music Library.
  • Find similar photos – pictures that differ a bit, compare, and choose which one you want to keep and which one to delete.
  • Find similar folders – folders that contain duplicate and unique files.
  • Merge folders – move or copy the content from one folder to another. You can merge similar folders and any two folders on your Mac.
  • Restore removed files – if you removed some files by mistake, you can view the Removal History and restore files from the Trash.
  • Save and restore scan results – if you have not finished the current session and want to quit the app, enable this option to restore the scan results later.

So how to merge folders on a Mac? Follow these steps:

  1. Open Duplicate File Finder.
  2. Click on Merge folders in the sidebar.
  3. Add the folder you want to merge.
  4. Click Review.
  5. duplicate finder showing the window to merge folders

  6. Select the destination folder. You can choose one of the folders you added or a new empty folder in any location on your Mac.
  7. duplicate finder showing folders to be merged

  8. Click Review & Merge.
  9. Confirm the action by clicking the Merge button.

Note that the merge option is also available in the Similar folders tab. You should use the new option only when you want to merge folders without scanning them for duplicates.
