Instantly find duplicated files on your Mac

It’s surprising how much disk space duplicated files such as music, videos and photos can take. The Duplicate Finder is a simple and effective tool designed to find those files which are hogging space on your hard drive. The Duplicate Finder uses an SHA-1 Checksum to compare files instantly and detect whether they are duplicated. It’s integrated with iPhoto and you can add as many or as few folders as you like for scanning. The Duplicate Finder also looks great – it has been optimized for OS X Lion in full-screen mode and for MacBook Pros with Retina displays.
