Cisdem Duplicate Finder for Mac helps you find duplicate files that have identical content regardless of name and displays them in an easy-to-understand report. The program ensures 100% accuracy, you can keep the best instance of each duplicate item and reclaim more space on your computer.



Cisdem Duplicate Finder uses an advanced scanning algorithm to compare files based on content, not just name, time, or size. With its advanced and configurable scanning engine, you can easily control where and what files to be scanned.
  • Scan files of a particular type or size for fast scanning.
  • Set up ignore list to keep specific files or folders untouched.
  • Find duplicate images, videos, music, documents, archives, etc.
  • Support external hard drives and network volumes.
Feel annoyed to find Photos or Music app stuffed with the same copies of a photo or a song? Get harder to search for a wanted photo or music track? Time to tidy up your media library! With an enhanced scanning algorithm, Cisdem Duplicate Finder can quickly filter out duplicates in Photos (iPhoto) and Music (iTunes), in the meantime, keep app file structure.

Search similar images smartly

Similar images eat up space too. You can use Cisdem Duplicate Finder for macOS to detect and remove similar images that are nearly identical with slight differences. It finds a series of shots and helps you keep the best picture after continuous shooting.

Easily find out all unnecessary duplicate files

Group duplicate files into different categories: Documents, Images, Music, Videos, Archive, Packages, etc., display duplicates by name, size, count or type, show what duplicates take up the most space, find specific files with the built-in search tool and auto mark duplicates basing on your selection rules for easy removal.

Three steps to take the pain out of duplicate files

Trust Cisdem Duplicate Finder to auto select duplicates and keep the originals intact. Add your own autoselect rules, like automatically marking the oldest/newest duplicates, or smartly selecting by filename/prioritized location. Duplicate files can be moved to Trash, custom folder, or deleted permanently. Scan, Report and Delete!

Note: The delete function is disabled in the demo version.
