You can import items from an external electronic calendar into a FirstClass calendar, or export calendar events and tasks from FirstClass. Imports use vCalendar (a .vcs file) or iCalendar (a .ics file) format. These are common formats for transferring information between applications. Exports use vCalendar or Excel format (a .csv file). Excel format consists of comma, tab, or semicolon delimited data.
