Duplicate File Finder allows you to find not only duplicate files and folders, but also Similar folders. Similar folders are nearly identical, and contain both duplicate and unique files. They are presented in a convenient way for you to quickly compare them and identify unneeded copies.
It may happen that one folder has several similar folders at the same time. The app shows all similar folders in one list, so it’s easy to review them and decide which files to remove and which ones to keep.
Under the visual representation, both duplicate and unique files are displayed. Please note that the app prevents the removal of unique files, so you don’t have to worry about unintentionally removing files you need to keep. Only identical files are able to be selected for removal.
When you select the files, a red circle appears over the current folder icon and shows the number of items selected within it. There is also a gray white sign, which shows how many duplicates are kept in a similar folder.
