# Remove duplicates with Smart Cleanup

Gemini thoroughly compares found duplicates on the last stage of the scanning process. In particular, it analyzes file creation and modification dates, extensions, paths, etc.

As you use Gemini, the Smart Selection algorithm learns the way you make choices and applies this experience to future sessions. Therefore, Gemini becomes smarter and more precise at automatic selection with every session.

After the scanning process is completed, you can instantly run Smart Cleanup, which removes only 100% safe duplicates by default. However, note that after using Gemini 2 a little while, it may offer adding some cleanup rules that enable Smart Selection of similar but not identical files.

1. Review Gemini’s scan results.

When Gemini completes a scan, it presents you with a summary that lets you find out what kind of duplicates are on your Mac and how much space they occupy.

- Total size of duplicates: Look at the middle of the chart.

- Size of files selected for automatic removal: Check the right side of the screen.

- Size of duplicates by category: Hover over a colored section of the chart to see category name and size.

2. Take a closer look at duplicates.

You can skip this step if you don’t feel like going through all duplicates - just move to automatic removal and check the way Gemini’s Smart Selection works.

- View all duplicates within a category: Click on the corresponding section of the chart.

- View all found duplicates: Click Review Results or click in the middle of the chart.

3. Remove automatically selected duplicates: Click the Smart Cleanup button.

There are some situations when Gemini has nothing to smart-select. This usually happens when you have cleaned your Mac recently from duplicates, and there are only similars that require your attention. This may also happen if you have added some files to the Never Select or Ignore List.

Note: By default, Gemini moves all of the selected duplicates to your Trash folder. This way they remain easily restorable. You can, however, set Gemini to remove duplicates permanently, or select another destination folder in Preferences.
