FileSync application is a component that is associated with Food Service (Table Service F&B only) module. This application manages local data for offline operation and centralizes data for a specific group of salespoints. FileSync runs in the background, keeping an up-to-date local copy of all Sales data that salespoints default to in the event of a network failure. After the connection with the database is re-established, the Sales data is re-synchronized with the database and operations continue as normal. This is an optional application and is not necessary for the operation of the Food Service module.
