I am seeking Native File Access Pack for NW 5.1

Perhaps a reader of this N.G. has archived somewhere the
NFAP for NW5.1 download, filename: nfap_51fcs_830a.exe
or even the NFAP CD-ROM in some dusty cabinet.

NFAP for NW5.1 has been officially unavailable for a
number of years; your help in finding it will be
very much appreciated.
