What is An ICS File

An ICS file is a standard file format used to store calendar information. ICS files are plain text files that allow users to manage calendar information such as events, meetings, schedules, to-do items, etc. ICS files are easily readable by Google Calendar, Apple Calendar, and Microsoft Outlook Calendar.

The ICS file contains essential event information such as the start and end dates, summary, location, description, attendees, reminders, etc. ICS users share events with multiple people through email clients.
