Useful and quite easy to use

I am amazed how many duplicated I have on my computer, and the program is fast and relaible in finding these. There are several options to remove the duplicates, either one by one or in bulk. To navigate within the program could be a little more intuitive (I have not figures out yet how to do a new scan without quitting and restarting the program), but other than that it does what it advertizes well.
The only thing I see that is problematic (and I do not see a solution to this) is that there are sometimes good reasons to keep duplicate files in different locations, and obviously, using the auto remove option is in such cases something you do not want to use.

Finds duplicates you never knew you had

I always thought I was pretty careful not to create a lot of useless duplicates. I'll have to rethink that, After using Macs for about 25 years, here and there unintentional duplicates have been created. I guess that's not surprising, with hundreds of thousands of files on my primary hard drive alone. Imagine my surprise. Over 250 GB. Now that's read savings. It can take a long time to do the main hard disk and even longer to be sure you're keeping what you w#ant, but the space savings are worth it.

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The application UI is a little bit outdated but not too hard to understand.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.
