A duplicate file finder is an app designed to detect duplicate files. Such apps use particular algorithms to compare files and identify the duplicates. Different apps may use different algorithms. For example, the algorithm PhotoSweeper uses can only handle images, resulting in its inability to find other types of duplicates. Easy Duplicate Finder uses SHA-256, which is a bit slow. Cisdem Duplicate Finder uses a combination of algorithms, leading to high performance in the detection of various types of duplicate files.

Safe support for Photos and iTunes (now Music)

Unlike on Windows where photos and music files are stored in normal folders, the photos and songs on your Mac are typically stored in Photos Library (managed via Photos app) and iTunes Media (managed via iTunes app) respectively. The fact is that many duplicate file finders for Mac will consider Photos Library and iTunes Media normal folders when searching for duplicates in the two places. As a result, they will damage your library or cause the loss of files or related data. To safely delete these duplicates, you need to use an app designed for Photos and iTunes.

There are other criteria to consider. The two ones above are the most important.

The app supports finding the double files in normal folders, iTunes and Photos and is capable of detecting duplicate photos, duplicate audios, duplicate documents and some other types of duplicates.
