+Enable the Quick File Access support. Tape positions for each

+.Ar file
+which is used by restore (if called with parameter Q and the filename)
+to directly position the tape at the file restore is currently working
+on. This saves hours when restoring single files from large backups,
+saves the tapes and the drive's head.

+It is recommended to set up the st driver to return logical tape
+positions rather than physical before calling dump/restore with
+parameter Q. Since not all tape devices support physical tape
+positions those tape devices return an error during dump/restore when
+the st driver is set to the default physical setting.
+Please see the st man page, option MTSETDRVBUFFER, or the mt man
+page, on how to set the driver to return logical tape positions.
+.Pp
+Before calling restore with parameter Q, always make sure the st
+driver is set to return the same type of tape position used during the
+call to dump. Otherwise restore may be confused.
+.Pp
+This option can be used when dumping to local tapes (see above)
+or to local files.
