This is a lifesaver. A perfect UI, and a powerful featureset.

The other reviews here are completely mistaken. I’ve been testing software professionally for 15 years, I’m head of a software development department at a major company.

This program is exceptional, and a life saver, so I feel obliged to correct the misinformation from the other reviews:

- Someone said it only makes a copy in the trash, it doesn’t actually move the file to the trash. Uh, no. You’re high. I tested this under a microscope before I unleashed it on my precious music collection. It deleted the track from the iTunes library, deleted the physical MP3 from its location while I watched it disappear, and it then showed up in the trash. Next.

- “A script that used to be free” - my god you people are ungrateful. Right now, Dupin is still being sold for 15 bucks on the web. But here on App Store, the price is only $5.99. That’s awesome. You’re not entitled to have someone else’s hard work for free.

- Someone wrote “doesn’t work at all - no iTunes duplicate manager”. You sir are in a coma and should not be allowed near software, let alone software reviews.

With 15 years of building and supporting enterprise web applications and native apps, I learned to test software, but I also learned that “the user is an idiot”. We can say by extrapolation that the user should not be allowed to write reviews that affect the livelihood of the software developer.

I had a massive “previous itunes library” folder with 80GB of music, while my main itunes folder had 50GB of music, leaving me in hell. Tons of those files are my own compositions recorded on my mac or a studio. Meanwhile, Time Machine could no longer run until I deleted files and created space. I needed a program I can trust, to help me consolidate my bifurcated collection in order to free up many GB, that’s why this turned out to be a lifesaver.
