What is a .ICAL file?

ICAL is an iCalendar event or calendar file. Opened by most calendar apps.

Did you know
  • Apple’s Mac calendar app was named iCal from 2002 until 2012, a name licensed from Brown Bear Software, which had been using it since 1997.
  • Content lines in an iCalendar file may be at most 75 octets long - anything longer is folded onto the next line, which starts with a single space.
  • Beyond events, the format defines components for to-do lists (VTODO), journal entries (VJOURNAL) and reminder alarms (VALARM).
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
.ICAL 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.
