A method for analyzing the storage capacity of a portable storage device is disclosed. The volume allocation information is divided into multiple sections. The method directly accumulates pre-stored results of the sections that do not need to be updated and reads the sections of the storage medium that need to be updated to obtain the allocation information. A method for analyzing the storage capacity of a portable storage device starts a delay period to count time. During the delay period, the updating process is not executed. After the delay period is reached, the volume allocation information that has been changed during the delay period is updated in an accumulated manner. A method for analyzing the storage capacity of a portable storage device restricts the number of the scanned allocation information sections to enhance the efficiency of the normal accessing process.
