Allows enabling or disabling a notification when disk space is low. This applies to all users on the device.
Setting policy to Enabled, an notification will be shown when remaining disk space is low.
Setting policy to Disabled or not set, there won't be any low disk space notification.
This policy is ignored and the notification is always shown if the device is unmanaged or there is only one user.
If there are multiple user accounts on a managed device, the notification will only be shown when this policy is enabled.
