An information processing apparatus that correctly handles moving image files recorded for a period straddling midnight. Moving image files recorded for a period straddling midnight are processed as having the day on which recording of those moving image files began and the next day as their recorded date. When conducting a search by date, for example, in addition to the actual recorded day, the next day is also included in the search results of a designated search, thus enabling the user to search for the moving image files without having to recall whether or not they were recorded for a period straddling midnight.
