Gemini 2: The Duplicate File Finder is brought to you by the team behind CleanMyMac 3. Removing clutter and recovering disk space are our specialty, so we made a duplicate cleaner that does both like a pro. Get yourself Gemini 2 and you will...
Free up gigabytes of storage space:
* Find duplicate files of any kind: pics, music, docs, you name it
* Identify duplicate folders, too
* Delete duplicates on external drives and network volumes
* Remove duplicates in cloud storage like Google Drive and Dropbox
Organize your music and photos:
* Find duplicate photos in your Photos library
* Detect pictures that are similar, but not identical
* Spot iTunes duplicates

And if you’re wondering what tech reviews say about Gemini 2, wonder no more: we’ve gathered some of them below.
“I’ve been an active user of MacPaw’s Gemini software since its inception, and Gemini 2’s release today has made me fall in love with it all over again. In just the initial scan, Gemini 2 found more files and more places where I could intelligently clear and save space on my Mac.”
“If you want to clean up your Mac, but are trepidatious about digging around in your files and accidentally deleting something important, Gemini 2 has a lot to offer and makes the whole process very simple.”
“With Gemini 2 there’s little reason to fear duplicates. It has a polished, intuitive user interface and the brains to differentiate copies from originals by testing them against nearly a dozen different parameters. It’s also much faster, especially compared to digging through thousands of files and folders the old-fashioned way.”
Introduced full support of macOS Mojave.
Ratings and Reviews
Great at finding duplicates and similars!
I just got rid of over 30G of duplicate files, some of which have been floating around for a decade or more. I found the interface fairly easy to use (though at times got a little mixed up and had to remind myself to select the one I want to DELETE, not KEEP!) It’s great at identifying duplicates… but don’t expect it to be 100% spot on. I did have to make some manual changes after the scan, and that did take a little time, but far LESS time than making a manual comparison to all files scattered across three hard drives. I would recommend always, ALWAYS, visually inspecting all matches before deleting. One thing I wish it would do, for when it finds duplicates scattered between two folders, is remember which folder you kept them in (much like it remembers whether you prefer older or newer, higher or lower resolution (or bitrate)). It’s probably a little bit more complex an algorithm to track, so I understand why it’s not part of the patterns it can detect. Also, it would be nice if it could flag any folders that were rendered empty after a purge, but I understand that, too, is probably above and beyond.
Great… but some crashes for large data scans
I was an owner/fan of Gemini vers 1.0 and have recently purchased this version as well. Despite the feedback below, I think its probably the best application for what it does.
Here’s what I think works really well, and what I think not so much:
- The duplicate detection is spot on. I’m always paranoid about it not actually selecting duplicate files. More often than not I trust but verify. I’ve never had it screw up the duplicate finding.
- The scanning works quickly.
- I’m enjoying the smart behavioral selection feature.
The Not so Well:
- It may be because I have a LOT of files to sort through, but the app crashes a lot with big scans (>50GB duplicates?).
- Its very slow sorting through those big scans.
- Its tedious to review findings. When sorting I can’t select multiple files within a file set. i.e. if it finds multiple versions of a particular file, and want to manually select or unselect for removal. It has to happen one at a time, and there’s a delay for each one.
- I love I can export detected duplicates to a text file, but I can’t actually bring those back into the application to re-process. If there’s a crash it doesn’t always remember my previous selections, and this file export requires me to use another tool to process and remove.
best duplicate finder i’ve used
photography and drawing are my hobbies. i have a photo archive of over 25K pics and another with many hundreds of drawings. As you probably know, many apps like this just grab all versions of a pic that are close to each other or similar. Gemini is more fine tuned. this app detects small differences, which is great. It will notice if i change just a few lines on a drawing or alter a small part of a photo. the price doesn’t bother me - i paid for it once a couple of years ago, i keep getting the updates free, it always works well and i use it constantly. good value
