Duplicate File Finder is a tool to quickly find duplicates and easily remove unneeded copies. It shows a list of all duplicate files and folders and compares even similar folders.

Imagine you have several folders on your Mac or drive that contain identical and unique files. In this case, these folders are not duplicates, as they keep different data. The folders on the screenshot keep 2 duplicate files and 1 unique file. In Duplicate File Finder program they are called similar folders.
