What is a VCS file?
A .VCS file is a vCalendar Event file. The Internet Mail Consortium developed the vCalendar standard to allow users to easily exchange calendar and schedule information across different platforms. These files store data in a plain text format, detailing event parameters such as the start time, end time, location, and description.
While usually containing calendar data, .VCS files can sometimes be associated with other exports. For example, some exports from the Huawei Calendar app use this format. In rare cases, older systems and apps like WhatsApp have used the .VCS file extension for voice messages.
How to open VCS files?
You can open standard .VCS files with most modern calendar and email applications. Programs like Microsoft Outlook, Apple Calendar, and Google Calendar support importing these files directly. Because the standard vCalendar format relies on plain text, you can also open and read the raw event data using simple text editors like Notepad++ on Windows or TextEdit on macOS.
