Ratings and Reviews

Good tool. Gets the job done.


The application UI is a little bit outdated but not too hard to understand. The functionality is well designed and fixed my particular issue. I am consolidating manual backups I have created over the years, so there are lots of file duplicates in each backup. This tool allowed me to merge all backups into one by removing duplicates.

it works


This ap works great for removing duplicate photos from my apple cumputer. Easy one click and done.

Useful but Has Issues


I used to program to identify duplicates in 250k files. It did a great job finding them although, as you can imagine, it took a while. Perhaps the issue I am going to identify is already resolved and/or I missed it in the screenshots on their website. However, if I look at the results of the scan of all those 250k files and allow it to auto pick one out of the duplicates to be saved and then just delete, for example, jpg files, I cannot go back from the Remove screen to the original scan and decide which files I want removed next. There doesn’t appear to be a way to either do that with a Back button or with a Save of the scan-to-date. So what happens is that the now 248k of files all have to be re-scanned. Again, given the size, this is a time consuming process. On the pull-down menu there is a Save and Save As item, but I could not find a way to select it and save the Scan in its current form. I do a lot of photography and Photoshop, so in the process multiples are created and this program would be good for cleaning up the mess if that simple issue of saving a scan could be addressed. All of that said, there may be a way to do this and I just missed it on their website. I would be more than happy to be corrected and change the rating. I have another 30tb of drives to scan, so being able to remove some files and then go back and review the remaining duplicates would be a big help.
