Abstract

A data synchronization method for a mobile device is provided for effectively synchronizing metadata between a database and a file system of the mobile device. A metadata synchronization method of the present invention includes resetting, when an external storage is connected, an effective value of metadata and a global variable; comparing, when the external storage is disconnected, each file information item managed in a file system with each metadata item managed in a database; replacing, when a file information item includes a metadata item, the effective value of the metadata item with a value of the global variable; and deleting metadata items with an effective value not identical to the value of the global variable. The data synchronization method of the present invention facilitates synchronization of the metadata and file information of the data stored in the external storage device.
