# Prevent accumulation of new copies

Duplicates Monitor is Gemini’s sleepless companion that resides in the status bar 24/7 and ensures no copy is created unnoticed.

When you open Gemini 2.8.0 or higher for the first time, Duplicates Monitor is launched too. It starts watching locations you’ve just cleaned from duplicates and alerts you as soon as a new copy is detected. The Monitor focuses on duplicate files and skips duplicate folders and similar files.

Note: If you don’t want to get notifications about new duplicates or would like to disable the Monitor, change Gemini’s preferences. Open Duplicates Monitor, click on the gears icon in the lower-left corner, and choose Preferences. On the Duplicates Monitor tab, deselect the corresponding checkbox.

Add new locations for monitoring

- Automatically: Remove duplicates with Gemini 2, and it will add the current cleanup location to the Monitor’s list.
- Manually: Open Duplicates Monitor, click on the gears icon in the lower-left corner, and choose Preferences. On the Duplicates Monitor tab, click (+), navigate to the desired folder, and click Open.

Remove locations: Open Gemini 2 Preferences and click (x) next to the location that doesn’t require monitoring.

Review newly created duplicates

Duplicates Menu shows you only the name and location of a new copy, but you can view its twins in Gemini’s main app.

- View in the Finder: If you just get a pop-up notification, click on the magnifier icon in the lower-right corner of the file icon.
  Alternatively, open Duplicates Monitor, click on a menu next to the file you want to have a look at, and choose Show in Finder.
- Compare duplicates: If you just get a pop-up notification, click Review. Otherwise, open Duplicates Monitor, click on a menu next to the file you want to compare with its duplicates, and choose Review.

Remove a new copy: If you just get a pop-up notification, click Remove. Or, open Duplicates Monitor and click on the trash bin icon next to the unwanted duplicate. Note that in both cases, the file is placed in your Trash folder, so you can bring it back in case of a mistake.

Hide a valuable copy from Gemini 2: If you just get a pop-up notification, click Add to Ignore List. Otherwise, open Duplicates Monitor, click on a menu next to the file you don’t want to be offered for removal, and choose Add to Ignore List.

Change the ignore list: Open Duplicates Monitor, click on the gears icon in the lower-left corner, choose Preferences > Ignore List tab. Use (+) to hide more files from Gemini’s scanner and (-) to make files visible again. For more information about the Ignore List feature, read this article.
