Hello, net:

     A friend and I are working on a program which will end up
copying lots of files to lots of floppies.  We need to know how to
calculate how many blocks a group of files will use on a floppy,
including the overhead for directory entries, etc.  We would like
the user to be able to select a bunch of files and have the program
be able to tell
    1) if the files will fit on a given floppy,
    2) how many blocks will be used, and
    3) how many blocks will be left.

(Ok, so 3 should be easy if you know 1 and two.)  So how
does one (or in our case, two) go about calculating such things.
Your help is greatly appreciated.
