While there is a factor of 5 or more orders of magnitude in byte capacity,
the capacity of what they will hold is unchanged.  A non-trivial MS WEIRD
file will no longer fit on a floppy.  An OS will not only no longer fit on
a floppy, some won't fit on a CD-ROM!

Data will always expand to fill the available capacity  - Boyle's law


MICROS~1 has certainly done their part to keep Moore's law and the
software variant of Boyle's law on track.
