Ratings and Reviews
Fast, Elegant Design and Worth the Upgrade
DFF has been wonderful in helping me to remove duplicate files after migrating three portable hard drives onto one large disk. It saved me 415GB of file space out of the original 1.9GB. I removed thousands of duplicates within less than a day after years of copying files from one drive to another to create redundant copies.
The duplicate folders and similar folders features are well worth the upgrade to remove multiple copies of directories at once, instead of removing each file seperately. This saved me a great deal of time as I had multiple copies of photo directories.
The interface is fast and elegant. DFF took about an hour or two to analyze hundreds of thousands of files (1.9GB). It neatly organized them so one could remove duplicate folders, remove duplicate files in similar folders, and leave the unique files behind. All other files can be removed one at a time, and “Auto-Select” saves time clicking on which version you would like to remove. The application also safeguards you from removing all copies of a single file or directory by forcing you to enable that function and warns you politely before marking all copies for removal, if you chose to do so manually.
Thank you for this wonderful application!
Thank you for such detailed review!
Since you have PRO we recommend to use "Select Duplicates in Folder" feature to select duplicates in bulk when you need to find duplicates in several folders or disks. The feature allows you to specify the folder to remove duplicates and another one to keep original files. https://nektony.com/duplicate-finder-free/select-duplicates-in-folder

I’m so glad I found this!
I almost bought a similar service online for $40 (additional $20 to scan folders and similar files, which this does). This app is only $5 for the upgrade to delete files and it is awesome! SO worth the price. And way faster! I just did the scan only (free) with the other service, and it took several minutes. This app takes seconds to find, and then to delete files after you tell it to.
The interface is also really great, and it’s easy to use.
There were a few files that it wouldn’t delete at first, because they were on a “never select” setting in the app, which I changed and then deleted ALL duplicates.
I’m surprised that I had up to 6 (maybe more) duplicates of some things! I just saved so much space. Happy!
Thank you for your feedback!
Happy to hear you got the right tool.

Wow..Life Saver Plus. Look no further…...
I have used others with little success and a fair expenduture. I downloaded this today and withut even going through the tutorial I gave it a shot. I was stunned. I knew I had a huge number of duplicate fies, folders. photos et al and Duplicate File Finder in a matter of moments found 17gb worth of documents only. Very impressed. Enough so I will spend the $5.00 immediately. This program is great, easily manueverd and has alredy made my life easier removing files that I have saved on numerous occasions for a number of reasons. New Macs, external drives, etc. Thank you, Thank you. I will be telling all of my Mac family and friends that this is a no brainer. I was burdened with a monumental task and I can now give a resounding "Sigh of Relief" .
With Family Sharing set up, up to six family members can use this app.
