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The application UI is a little bit outdated but not too hard to understand.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

I Like This App, But It Has Missed Some Duplicates

I have been using this app for a few months. It is easy to use and faster than some other tools I’ve used. I like the interface, especially how it presents the results of the scan. You can actually scroll down the list and there’s a window for content preview. But, there are duplicates that it does not find. I have encountered movies files (MP4, WMV, etc) that exist in different folders, have different names, but are otherwise identical (hash is identical) and they do not show up in the results. It’s strange because it does find duplicates, it just seems to miss occasional files. And, I’ve noticed that the files it misses, it always misses. It’s not like you can run the scan again and it will find it. I’ve looked at the files it misses and can’t make heads or tails of why it misses that particular file. I didn’t even know it missed files until I was seaching for a file and found it in two locations. Identical files that were not discovered. So, the problem is that I really don’t know how many duplicates are left on my Mac unless I’m willing to manually do some exhaustive process. In all fairness, I have to note that I was using another tool, Find Duplicate Files, that also missed these same duplicate pairs. Just can’t figure it out why it happens and I’m sure that I’ve got Gigs of space that should otherwise be reclaimed.
