Choose the Fetch... menu item to retrieve a copy of
  the specified object or objects from the CMS library.

  The object can be an element name, a group name (CMS
  will fetch the most recent generations of elements
  in the group), a wildcard expression, or a list of
  these separated by commas. CMS fetches the most recent
  generation on the main line of descent unless you fill
  in the Generation field.

  Fetch delivers a copy of the specified generations to
  your current default directory.  The generation is not
  reserved, and CMS does not allow you to replace it.

  CMS allows you to fetch a generation that is already
  reserved, and notifies you of any current generation
  reservations for the element.

  If a version of a file with the same name as the element
  already exists in your current default directory when you
  execute the fetch transaction, CMS notifies you. A new
  version is then created with the next higher version
  number.
