Sources:Starting October 13, 2020, we’re changing the retention policies for items in the Trash in Google Drive. With this new policy, any file that is put into a Google Drive trash will be automatically deleted after 30 days. Previously, trashed items would be retained indefinitely until the trash was emptied by the user.
Extended rollout (potentially longer than 15 days for feature visibility) starting on October 13, 2020.
