Abstract
A version management system and method, enabling discarding of old version content files through simple and low-load processing. Storage periods and holding periods are allocated to a plurality of storage elements provided in a non-newest file storage unit. When a newest version content file is registered, the content file is stored in a newest version file storage unit. A content file which has become a non-newest version content file due to the version upgrade is transferred from the newest version file storage unit to be stored in the storage element to which is allocated the storage period corresponding to the date of the version upgrade. When the above corresponding holding period has elapsed, content files within the storage element are all simultaneously deleted.
