An example computer-implemented method to determine if an event was triggered by an action performed by a client synchronization module begins with receiving an event from an operating system. The event can be associated with a content item. The computer can then compare the event to a log. The log can describe one or more recent actions performed by a client synchronization module. The computer can then determine whether the event was triggered by a recent action in the log. When the event is triggered by a recent action in the log, the computer can ignore the event. When the event is not triggered by a recent action in the log, the computer can process the event.
