When share a file/folder, user can enable the share notification.
When edit the share, can modify the notification.
There are 3 notifications. Assume user1 is the owner of the share. And the folder is shared to user2. Here are how the notification works:
- Send email notification when file is downloaded: when user2 downloads files from the share, send email notification to user1.
- Send email notification when file is uploaded: when user2 uploads files to the share, send email notification to user1.
- Notify user when file/folder is changed: when user1 updates files on the shared folder, notify user2 about the change
