Gemini 2
Gemini 2 is the more polished of the two. Beyond finding exact duplicate files, it uses a similarity algorithm to catch near-duplicates — like two versions of the same photo where one has been slightly edited, resized, or re-exported. For Mac users with large photo libraries built up over years of iPhoto, Photos, and iCloud migrations, this makes a meaningful difference.
The interface is designed for non-technical users. After a scan, Gemini 2 presents a clear visual summary of what it found, how much space is at stake, and what it recommends removing. Crucially, it asks for confirmation before deleting anything — you stay in control.
Best for: Users with large Photos libraries, anyone migrating from an old Mac, people who want the most thorough scan possible.
How to get it: Gemini 2 is included with Setapp, a $9.99/month subscription that also includes CleanMyMac X, BusyCal, Bartender, and 240+ other Mac apps. If you’re not already on Setapp, it’s worth considering just for the value across the full library.
Duplicate File Finder
Duplicate File Finder by Nektony is a free download from the Mac App Store and it does the fundamentals well. It scans folders you select, finds exact duplicate files, and lets you remove them. The interface is clean and straightforward.
The main limitation is that it only finds exact duplicates — same file, same content. It won’t catch near-duplicate photos or similar documents. For a basic cleanup of a Downloads folder or a project directory, that’s usually fine. For a deep Photos library clean, you’ll hit its ceiling.
The free version handles most use cases. The paid upgrade adds batch operations and a few convenience features, but most users won’t need it.
Best for: Quick, targeted scans of specific folders. Users who want a free solution and don’t need Photos library analysis.
Which Should You Choose?
Choose Gemini 2 if:
- You have a large Photos library with years of images
- You’ve migrated from an old Mac and want a thorough clean
- You’re already on Setapp or willing to subscribe
Choose Duplicate File Finder if:
- You want a free option
- You just need to clean a specific folder
- You’re scanning for exact duplicates only
For most Mac users doing a real storage cleanup, Gemini 2’s similar-file detection and Photos library integration make it the stronger choice. The Setapp route especially makes sense if you’re not already paying for individual apps it replaces.
