iCalendar files may be updated on the Internet by WinDates or other calendar programs. WinDates provides a refresh function which downloads the latest calendar data from a subscribed calendar and updates your local version of the calendar.
When the calendar refresh occurs, WinDates downloads the iCalendar file from the subscribed web address and compares each event to those in your local WinDates event file. New events are added to the file, updated events are replaced and you are prompted whether to delete local events no longer found in the subscribed calendar.
Calendars may be refreshed on demand through the Calendar Manager. Calendars are also refreshed automatically prior to publishing the calendar. This refresh ensures that you download the latest calendar changes prior to publishing which guards against overwriting changes to the calendar made by another computer.
