Opening ICS files

What is an ICS file?

Files that contain the .ics file extension are created by a variety of calendar and scheduling applications. These calendar files allow different users to store calendar information within a text file. That text file can then be stored on the Internet and can be synchronized with other users' calendars. A user can stay updated regarding another user's calendar by "subscribing" to that calendar. This tool often helps administrative assistants help manage their executive's schedules and helps project teams stay coordinated.

Some of the applications that use the .ics file extension include Apple's iCalendar, IBM Lotus Notes and Microsoft's Outlook email and calendar application. The Open Source Bedeworks software project has also been reported to support the ICS file format.
