Gemini 2 by MacPaw promises to locate and remove duplicate files on your Mac, wherever they may be. This can become a real problem, especially if the duplicate files are big to begin with, like movie files, and somehow files seem to replicate almost by themselves somehow. Gemini 2 scans your whole disk fairly quickly, even if it’s over a Terabyte. My 41.1GB documents folder took just 42 seconds (but mind you, this was on a fast SSD drive). Once it has achieved the scan, the software displays the scan results and you can hand-pick the files to erase, or let a feature called Smart Select do all the work, which you might consider of you have regular backups and indeed, your last backup was very recent.
You may have some files that have duplicates you want to keep. In Preferences, you can set Gemini 2 to just scan for duplicates or for ‘similar’ files as well, and you can set a file size for it to scan for too, up to 200MB, or leave it on Automatic (under General>Minimum File Size).
There’s an Ignore List tab if you want to add folders you don’t want scanned at all, and you can also choose certain file extensions for it to ignore if you wish. There are parameters for Smart Selections here, and you can select options for removal, too – straight to the Finder’s Trash, or move to a folder, or remove permanently (into the Trash then empties automatically).
Gemini 2 finds files that look alike, see how they differ, and lets you delete those you decide you don’t need.
Going deeper — Gemini scans your iTunes Library to find multiple copies of songs, too – it can tell copies from originals. Perhaps the best thing is that it learns to select duplicates the way you do. Gemini’s algorithm remembers what you delete and what you choose to keep as you go through the list of duplicates it throws up.
Gemini 2 asks permission to open Photos’ Library to look for duplicates there, too – you can turn this on as a default behaviour (called ‘Always Open’).
Once you start selecting, say, every second file, Gemini figures out whether you’re selecting the newest or oldest version and asks if you with this to be the default behaviour. Affirm and it selects the rest for you on this pattern, which saves a lot of scrolling and clicking.
It works in English, German, Spanish, French, Russian, Ukrainian, Italian, Polish, Dutch, the Portuguese of Brazil, Chinese and Japanese.
Conclusion — Once upon a time, utility software may have been good but it could be obtuse to use – and almost worse, it was often difficult to look at. Programs like Gemini 2 and stablemate Clean My Drive 2 look fantastic, work well and don’t require much manual reading, if any, to use effectively.
Here’s to that.
What’s great — Fast. Looks fantastic, too, so Gemini does what it promises in fine style.
What’s not — If you don’t have a backup, don’t use this software or anything like it. Deleting duplicates is always a little terrifying.
Needs — Anyone worried about their drives filling up unnecessarily, fans of good housekeeping, those worried about space (Macs run better with some ‘head-room’ of
