What is a .VCS file?

VCS is an older vCalendar event file, the predecessor of iCalendar.

Did you know
  • vCalendar came first in 1996 and was soon succeeded by today’s iCalendar.
  • VCS uses vCalendar 1.0, defined by the Internet Mail Consortium, which directly inspired the iCalendar standard that succeeded it.
  • iCalendar, the .ics successor, is now defined by RFC 5545 and supports recurring events, time zones and attendees that vCalendar lacked.
What Analyser reads
Open personal-information files: iCalendar .ics/.ical and .vcs (events, times, recurrence, organiser/attendees), vCard .vcf contacts (fields + inline base64 photo), LDIF directory exports and Windows .contact - with Outlook .msg/.pst, IBM Notes .nsf, Exchange .edb and Outlook Express .dbx identified. Email messages (.eml/.emlx/.mbox) now open in a full viewer - see Email above.
Depth of analysis
.VCS is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
