Looking for info about .ifb files
ScheduleWorld generates .ifb files. I had never heard of .ifb files before. It looks like they are iCalendar free/busy files. But Apple's iCal couldn't open them. Does anyone out there know more about .ifb files? A Google search isn't any help.
As indicated in Section 3.10 of [RFC2445], the URL of calendar object resources containing (an arbitrary set of) calendaring and scheduling information may be suffixed by ".ics", and the URL of calendar object resources containing free or busy time information may be suffixed by ".ifb".
The file extension of "ics" is to be used to designate a file containing (an arbitrary set of) calendaring and scheduling information consistent with this MIME content type.
The file extension of "ifb" is to be used to designate a file containing free or busy time information consistent with this MIME content type.
Macintosh file type codes: The file type code of "iCal" is to be used in Apple MacIntosh operating system environments to designate a file containing calendaring and scheduling information consistent with this MIME media type.
The file type code of "iFBf" is to be used in Apple MacIntosh operating system environments to designate a file containing free or busy time information consistent with this MIME media type.
The .ifb is mentioned in the CalDAV draft spec where it states:
