When you import a .vcs file, events are converted to FirstClass calendar events, and to-dos are converted to FirstClass calendar tasks. All imported calendar items are placed in your personal calendar. Any information that doesn't belong in FirstClass' calendar event and task fields is placed in the event or task bodies. To import external calendar items: 1       Choose File > Import > Import Calendar. 2       Select the .vcs file. To import a .vcs file attached to a message, select it, then choose Collaborate > Add to Calendar.
