How to Merge Similar Folders with Duplicate File Finder

Duplicate File Finder is the most accurate app for finding equal files on a Mac. The application allows you to find all the duplicate files and folders as well as similar photos on any type of disk. It also displays Similar folders. Unlike duplicate folders, which contain absolutely equal content, Similar folders contain both equal and duplicate files. With Duplicate File Finder you can review Similar folders and merge them. In this article, we will take a closer look at this feature.

Merging Similar folders will be especially useful for those users who are more focused on organizing disk space rather than saving it. Imagine you have a large number of similar folders. With Duplicate File Finder, you can compare these folders, then select and remove duplicates, while retaining the folders with unique files. As a result, you still have dozens of folders in which, over time, you may have difficulty in finding the files you need. But if you may want to take all these similar folders and merge them into one folder by discarding the identical files and keeping only the unique ones. In this case you can use the Merge folders option and complete your task in just a few clicks. Follow the steps below:

How to Merge Folders with Duplicate File Finder

Let’s take a closer look at each option:

  • Copy unique files – the unique files from one folder will be copied to another folder. As a result, you get two absolutely duplicate folders. Later you can remove the unneeded folder.

  • Move unique files – the unique files from one folder will be moved to another folder. Duplicate files from the source folder will be removed. As a result, you get the folder containing all the files from the initial folders.

    In our case, we were copying the content of folders 3 and 4 to folder 2.

In the case, you have files with the identical titles in folders you are going to merge, you can get several results after merging:

  • You have two duplicate files with the same name, size, and content in the source and destination folders. After merging folders, you will have only one file in the destination folder.
  • merge to folder

  • You have two different files with the same name in the source and destination folders. After merging, you will have both files in the destination folder. The one file will have the same name, while the other file will get the number index to its title, so you can easily identify it and rename, for instance.

  • You have two duplicate files with the same size and content but with different names in the source and destination folders. After merging, you will have both duplicate files with different names, as the app cannot decide which file to delete. You will have to remove unneeded duplicate after merging.

Merging similar folders allows you to combine dozens of duplicate files and folders, making the structure pretty much easier. Use the merge option to easily organize your files and don’t leave any duplicate space eaters behind. Keep your Mac clean from useless dupe items.
