Features

Find duplicate files as well as similar files

Gemini doesn't just compare files on computer based on file names. It also checks file content to provide high accuracy. We can end up with same files in different folders due to unintentional repeated downloads or imports. Gemini 2 can easily find them by scanning these folders at the same time.

It can also identify similar audio files and photos, such as photos taken from different angles. This feature is functional, but you can't customize how identification works. Therefore, it's not very effective.

Automatically select duplicates for removal

Once Gemini 2 duplicate finder finishes scanning for duplicate files, it automatically and intelligently selects files to delete, recommending which duplicates can be safely deleted. This can save you from manually comparing and removing duplicate files one by one. At the same time, you are able to manually select or deselect files. You can also control how automatic selections work by selecting the Oldest or Newest rule.

This is a very useful feature, as you can preview files to make sure you select the correct copy and don't accidentally delete important files. The preview pane supports multiple file types. You can preview images, play audios and videos, and even view document content.
