Systems and procedures for notifying users of changes to files in cloud-based file storage systems

摘要

Disclosed herein are systems and methods for generating notifications about files stored in cloud-based file storage systems. A first indication of a first change to the file by a first user is received from an external server where the file is assigned to a second user and stored by the external server. Subscription preferences of the second user are received. A notification reporting the first change to the file will be displayed on a mobile device associated with the second user if the notification category is allowed by the subscription preferences. The notification includes a graphical preview of the file, a file ID, and an identity of the first user.
