how to recreate vdir -f foo.fs in QNX 6.1

QNX USERS QNX6 - OS

I have a file foo.fs that was meant to be mounted in QNX 4 with a command like
vdir -n /fs/foo -f foo.fs

Unfortunately I don’t have access to QNX 4, only QNX 6.x. Is there a way to work with this file in QNX 6? Can the mount command do it?

I don’t remember QNX 4’s vdir has a -f option. Maybe that’s your own customized command?
If so, maybe it tries to mount the fs from a flat file. In QNX 6, you can do

mount -t qnx4 foo.fs /fs/foo

(assuming the “foo.fs” is in QNX 4 fs format)
