Speed up the performance of your Mac by finding and removing true duplicates of various files. Scan the drives and folders, access external and internal devices, iTunes and iPhoto databases. Remove the files automatically or view the list for manual management.

Cisdem DuplicateFinder offers to identify and remove duplicate files within specific drives you determine. With this tool you can scan both computer drives and folders located on external devices, as well as Apple applications like iPhoto, iTunes, and Mail. Providing smart scanning algorithms, the program has the ability to find true duplicates based on file content. The program is designed to help you delete duplicates in batches so that you can regain valuable free space.

The utility has a simple, clear-cut, and intuitive interface that allows you to manage the tool's functions with ease. Before enabling the scanning operation, you have the chance to specify the size rage to be taken into account when searching for similar files - this way, the files with shorter size than the one you determine are excluded from scanning. In addition, you can ask the program to skip Packages from scanning, as they usually contain a great number of files and slow down the searching process. While the scanning operation is in progress, you have the ability to see in real time the amount of scanned files, the number of found duplicates, and the size they occupy on the disk. Once the scanning operation is over, the tool offers to sort the results by file types and displays the categories of doublets in both pie chart and tab view. Optionally, the results are sorted by size, name, or file count. Prior to deleting the duplicates, you can preview the files with Quick Look or open them with Finder. The app provides two removing modes that let you either wipe out selected files permanently or send them to Trash folder.

To sum up, Cisdem DuplicateFinder provides you with an easy solution to unclutter the storage space of computers and devices by removing useless duplicate files. Consequently, the system will perform better, the running operations will complete in a shorter amount of time, and the disk will have enough room for storing information that is worth being kept.

Rock-solid handy little app. That's what I think. It's just 2.6MB, very light app. And it runs pretty well on my Mac Yosemite. Just need a moment, all the duplicates are removed. I highly recommend this app to all Mac users. Thanks to the developer!
