Step 2. View duplicates

Gemini 2 uses a sophisticated duplicate identification approach that compares both data lengths and multiple file parameters during the scan process. After detailed analysis is over, Gemini splits all found items into:

By default, Gemini suggests cleaning your Mac from exact duplicates only, while their originals are always kept untouched. Thus, you can remove duplicates directly from the summary screen without even previewing them. Similars, on the other hand, aren’t selected for removal by default because actually they are different files having minimum changes. So, if you need to clean up some disk space from similar files, you must switch to detailed results screen and make the choice.


Note: Don’t worry, Gemini always warns you when you try to select all available copies of a file (no matter, a duplicate or similar). Thus, at least one copy will be saved on Mac.


Further, Gemini gathers all found files into the following sub-groups:

Group File types
All Duplicates/Similars All duplicates/similars found during a scan, disregarding their type.
Applications Application files from any location.
Archives Archives and containers of different origin in ZIP, RAR, and other archive formats.
Audio Your iTunes library music and files in MP3, AAC, AIFF, APE, and other audio formats.
Documents Usually, text files in DOC, PAGES, PDF, PPT, TXT, XLS, and other similar formats.
Folders Duplicates of entire folders found within scanned locations.
Images Your Photos library images and files in JPEG, PNG, TIFF, and other image formats.
Movies Video files, including movies and podcasts of all known video formats.
Other All items that cannot be referred to any of the groups listed above. Such as contacts, calendar data, cache data, application plugins, etc.
Selected All files added to the removal list, including duplicates and similars.
