Outstanding performance and ability to control

Unlike less-useful products (Gemini being a great example), this product allows great options in determining how duplicates are selected. Options include path, path-length, file name, file-name length, search for dupe indicators (such as -1 or "copy" in the file name) and allows you to select with ease.

Also, unlike Gemini, this product doesn't try to think for you... which also means that it doesn't fail in that effort like Gemini so routinely does. I'm done with Cocoatech and Gemini. This product is my new (and only) duplicate file tool

After Much Research - Duplicate File Finder Pro WINS

After exhaustive research on duplicate file finders for Mac, I experienced Duplicate File Finder Pro as the fastest, most accurate, easiest to use, and the most cost effective duplicate file finder app available.

Also, after my experience with Yuriy from Duplicate File Finder's support staff, I have to say that Duplicate File Finder Pro is not only the best Mac duplicate file finder, it also has one of the speediest and most thorough support crew I’ve experienced in over 30 years in tech.

Thank you, Nektony for Duplicate File Finder and your outstanding support team! You made my life easier.

Worth buying the Pro version

After trying numerous duplicate finder apps on both Mac and PC, I finally bought this Pro version.

I like the fact they have a free version so you can try before you buy. It also interfaces with Photos so you can send photos to a Duplicates album first before deleting. That is handy when you don't use iCloud and instead sync your Mac and phone.

I just wish they had a PC version so I can clean up files on my gaming computer!
