A check code generating means 10 generates, based on metadata of files satisfying a designated condition, a first check code uniquely representing a characteristic of a first file set whose components are files satisfying the condition. Moreover, the check code generating means 10 generates, based on metadata of files satisfying the condition, a second check code uniquely representing a characteristic of a second file set whose components are files satisfying the condition.
