Extension=Disable
    Extension=Enable

    Allows you to change the automatic file extension attribute for a
    storage area when you copy a database.

    Use the Extension=Disable qualifier to disable automatic file
    extensions for a storage area.

    Use the Extension=Enable qualifier to enable automatic file
    extensions for a storage area.

    If you do not specify the Extension=Disable or the
    Extension=Enable qualifier, the storage areas are copied with
    the automatic file extension attributes that are in effect for
    the database being copied.

    The Extension qualifier is a positional qualifier.
