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.

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

Best Dup finder I have tried

Very easy to use, does not go just by just the file name, which is really important for me. It is FUN to use. I am getting dug out of the mess I have made on my external drive. I LOVE LOVE LOVE it. If you have thousands of files, this app will help get it under control. I wish I had found this years ago. And no, I do not know the author - promise. Wish I did- he is one smart dude for figuring out what people really need in a duplicate finder. Oh and the manual is amazing.. lots of detail and example screens.
Have been using this app for YEARS and still love it. Strong recommendation.
