Many Android devices, including those from Samsung and Google, often come with 128GB or less of internal storage, highlighting the need for effective storage management. The Clean tool in the Files by Google app helps users manage storage by identifying outdated files for deletion. Users can access the Clean tool by opening the app, selecting the Clean tab, and following prompts to delete unnecessary files. To permanently free up space, users must also delete files from the Trash tab. Pixel phone users can enable Smart Storage, which automatically deletes media backed up to Google Photos that is older than 60 days. Regular storage maintenance is important to prevent running out of space, and the Files by Google app provides tools for monitoring and managing storage effectively.
