File=file-spec

    Updates the database root file with the file specification
    for the storage-area-name parameter it qualifies. Use this
    qualifier to update the root when the file specification for a
    storage area has changed since the backup file from which you are
    restoring the root was created. (For example, if you have used
    the RMU Move_Area command since the backup file was created.)
    This qualifier does not change the file specification of the
    storage area it qualifies; its purpose is to update the database
    root file with corrected information. When you specify the File
    qualifier, you must supply a file name.

    See the Usage Notes for information on how this qualifier
    interacts with the Root, Snapshot, and Directory qualifiers.

    This qualifier is not valid for single-file databases. This is a
    positional qualifier.
