Abstract
In a file management system of the present invention, in order to efficiently manage a picture recording file that stores moving picture data such as television program, there is provided a property file for storing status information indicating a use state (such as reproduction count or reproduction portion, for example) of the picture recording file. According to the use state of each picture recording file, the status information indicating the use state is stored in the property file. In this manner, for example, when all the image recording file is displayed in a list, the use state of each picture recording file is acquired from the property file, making it possible to clearly present a user with a use state such as 'Not reproduced' or 'Reproduced'.
