The Duplicate Finder 4+

Works well to clearly identify duplicates, triplicates, etc. A lot of work required when deleting manually, however, since it won’t always list the file version that might be most appropriate to keep (i.e., if storage on multiple drives). Definitely a time-saver and will use it regularly.

It does what it advertises, but, has issues:

1. It over reports duplicate file sizes. The reported sizes include both the original and duplicate(s). So, in my case it nearly doubled the reported amount of wasted disk space.

2. The usability for this app is very poor. I much prefer Gemini (also on the app store), but Gemini doesn’t handle hard links, so I bought this instead. Unfortunately, this app still counts hardlinks as duplicates. I was confused by which file would get deleted, because often selecting a file caused the placement of the file to change, forcing me to double check that I did indeed select the correct file.

This is a very well designed and very functional app. I have saved myself MONTHS using this. I had almost 2000GB of RAW photos and files to sort. I feel confident trusting this application to not mistakenly delete non-duplicates. It reads/listens to/looks at all the files and creates a mathematically generated string of characters.. a fingerprint. I have waded through hundreds of it’s choices… it has never failed me. HIGHLY recommended.. also.. I purchased several other ‘sorting’ apps.. but this is the only one I use.

FEATURE SUGGESTION: PLEASE allow drag and drop into the post sort window without forcing me to click on ’new sort’. It’s a GUI error as far as I’m concerned. It’s counter intuitive. I have lost track of the number of times I’ve had to drop my selection of folders… go to the app and click new sort to get back to the folder drop window. Why do you even need that window? If you drag folders into the application.. clearly you want to reset and sort them. The drag and drop action SHOULD produce the same result as the “new sort" button. In fact.. if there are zero files it should accept new files automatically as a new sort.
