File recording device and imaging device

A file recording device includes a control unit (101) that controls a batch copy process which copies collectively a plurality of files stored in a first recording medium (300) from the first recording medium (300) to a second recording medium (106). When a batch copy process is completed, the control unit (101) records copy date and time identification information for identifying copy completion date and time to the first recording medium. The control unit (101) performs the control so as to compare the batch copy completion date and time indicated by the copy date and time identification information with recording date and time information on files stored in the first recording medium, to identify a file recorded in the first recording medium (300) later than the date and time on which the batch copy is performed, and then to copy the identified file to the second recording medium (106).
