Top 5 Best Free Duplicate File Finders For Mac


Duplicate files waste valuable space in your Mac. If you often save documents, photos, videos, music and other files in your Mac, there is a big chance that some of these files are redundant or duplicates.

And because they are normally saved in different folders or in other locations in your computer, manual removal of duplicate files becomes even more tedious and time-consuming.

Fortunately, there are duplicate file finder applications that are specifically designed to help you solve this issue. Here are 5 programs we recommend.


5. Decloner


Decloner promises to provide a high level of accuracy in finding and removing duplicate files using the SHA-1 algorithm.

If you like to scan a particular file directory for duplicates, simply browse through it and then click Scan. Scanning can take some time depending on the size of the directory or folder. It will then present to you the duplicate files and let you decide whether to trash the oldest or the newest one, or to trash duplicate files manually. All duplicate files that have been deleted will just be moved to the Trash so you can still restore them anytime unless you decide to empty the Trash.

Decloner supports QuickLook for faster and easier selection of duplicate file groups. It also shows detailed information of duplicate files. And while it works well on Mac computers, you can also use it for external drives.

Once duplicate files are found, you have the option to manually delete them one by one or use the Auto Select button to automatically remove all duplicates. You could use this application for both external and internal file storage.
