What is a VCS File?

A VCS file (with the .vcs extension) is a calendar file in the vCalendar 1.0 format. It was the original calendar data interchange format before the modern ICS (iCalendar 2.0) standard.

VCS files are still used by:

  • Legacy calendar applications
  • Older phone sync software
  • Some enterprise scheduling systems
  • Older email clients and PIM software

Good to Know

While VCS is an older format, the iCalendar Chrome extension fully supports it. You don't need to convert VCS to ICS - just drag and drop your VCS file and import directly.

Why Google Calendar Struggles with VCS Files

Google Calendar's native import feature is optimized for modern ICS files and has limited support for the older VCS format. Common issues include:

  • VCS files may not be recognized at all
  • Date/time parsing errors due to format differences
  • Missing event details after import
  • Encoding issues with special characters

The iCalendar Chrome extension solves these problems with a dedicated VCS parser that properly handles the vCalendar 1.0 format, ensuring your events import correctly.
