The copy you *did* post to the net has, in ASCII in jformat.com, the notice

   Copyright (c) 1983, 1984 Tall Tree Systems

so it doesn't look like public domain software to me.  In the file qdrive.bin
there is the copyright notice and a version number v2.30.  The .doc file
caused both arc and pkarc to throw up their hands in horror, so I don't
know what it contained.

Given the command you recommended in "readme.1st" the unpacked jformat.com
formatted a floppy disk at 322K, not the 401K requested.

I suggest anyone in receipt of the referenced posting erase it.
