All about Smart Cleanup

Gemini 2 includes unique sophisticated algorithms that compare files using a wide range of parameters to detect similarities and make suggestions. In particular, it automatically selects identical files ("duplicates"), which can be safely removed with a single click, without review. Originals of these files remain on your Mac after cleanup. This approach is called "Smart Selection."

To free up more space, Gemini 2 also filters out "similar files" that slightly differ from each other. These files require your review — Gemini doesn't offer to remove them automatically.

When the scanning is over, Gemini shows you the amount of disk space that you can retrieve through the cleanup of safe duplicated data. Here you can also check the types and size of found duplicates (use the diagram). Then, all you need to do is click the Smart Cleanup button. With this action, Gemini will move all duplicates to your Trash.

When you scan the Home folder, Smart Selection marks duplicates in Downloads and Desktop for removal automatically. However, duplicates in Documents will not be selected. The original file will remain completely safe.

As you use Gemini 2, it analyzes the way you make choices and offers to set new rules when it determines your selection preferences. For instance, it may suggest selecting all newer files by default or adding some cleanup rules that enable the Smart Selection of similar files.

You can see the applied rules in the "Smart Selection" tab of Gemini 2 Preferences. There you can disable/enable them as well as restore the default rules.

Gemini's Smart Selection helps you quickly obtain some free space, but you can make your choices manually too. Just switch to the detailed summary screen and select files you no longer need. On the extended view screen, you can also review and select similar files.
