I have seen this file created by a few programs which provide a
graphical interface to the CLI; unfortunately the only name of 
such a program which comes to mind is "CLI Wizard" which came
with my Amiga 2000 when I bought it in 1989 (so most people
probably won't have heard of it).  I believe that
what it does is store a list of files in the directory the first
time you ask the program to list the directory; then when you
ask again it just prints out the list from the .fastdir file.
(This sort of program usually has an "update directory list"
command.)

I don't know if there's anything "special" about creating such
a list, other than figuring out how to use dos.library calls,
which are not very well documented in the Commodore manuals.
