If you have a different iCalendar or vCalendar file somewhere, and you would like to merge its contents into your own calendar, add as a new resource or open it as a new window, choose this menu item. A good time to do this would be if you received a vCalendar with a few entries via email, for instance.
Escolla esta opción se ten un ficheiro vCalendar ou iCalendar algures e quixer incluir o contido no propio calendario, engadilo como un novo recurso ou abrilo nunha xanela nova. Un bon momento para o facer é, por exemplo, ao recibir por correo un vCalendar con algúns elementos.
