The IDiskQuotaUserBatch interface enables you to add multiple quota user objects to a container that is then submitted for update in a single call. This reduces the number of calls to the underlying file system, improving update efficiency when a large number of user objects must be updated. This interface is instantiated by using the IDiskQuotaControl::CreateUserBatch method.
