You asked for it, we’ve done this. Duplicate File Finder got a new update and the latest version 6.14 finds similar media files.

Duplicate File Finder is an application which finds all types of duplicate files and similar photos. After adding a feature to find similar photos on Mac, our support team began getting messages from the users, asking to find their similar music files as well. Since, our users’ feedback always inspires us to make the application better and even more useful, we started working on this task. However, before providing the screenshots on how to use the new feature, let us explain what we call duplicate and similar files.

What are duplicate files?

Duplicate files are the copies of a file on your computer. These files have absolutely identical content, size and extensions. They can have different names and can be stored in different locations on your disk. Duplicate File Finder compares the files’ content and meta-data and if they are identical, then they will be displayed as duplicates.

What are similar files?

Similar photos and similar music files in Duplicate File Finder are the files that can look as duplicates, however, their content slightly differs one from another. Imagine the Burst Photo mode on your iPhone. The series of these photos are similar but they are not duplicate. We call these series of similar-looking pics Similar Photos.

When it comes to similar music, make note, that we are not talking about similar songs by sound. Imagine you have two audio files of one song of a particular artist and particular album. The record time of these files might differ by several seconds or the record time and music track is the same, but some metadata is different, for example, one file contains a genre or comments. Due to this, even if it is the same song, we can’t display them in the Duplicates section as they have different data. In this case, Duplicate File Finder will display them in the Similar Media section. all similar media

So how to find similar media files on Mac? Follow these steps:

  1. Open Duplicate File Finder.
  2. Add the folder you want to scan. You can add your Music and Photos Libraries as well.
  3. Click the Scan button.
  4. Switch to the Similar Media section.
  5. Select the files you don’t need and click Remove.
  6. Confirm the action.

What are the benefits of Duplicate File Finder for Mac?

Duplicate File Finder from Nektony provides a set of unique features which you will not find in other applications. Here is a short list of them:

  • Similar Photos – find pictures that differ a bit, compare, and choose which one you want to keep and which one to delete.
  • Merge Folders – you can find Similar folders, compare their content and even merge them.
  • Restore removed files – in case, you removed some files by mistake, you can view the Removal History and restore files from the Trash.
