[net.micro.pc] backup/restore

I am new to the net, but I have read a couple of articles from people
on problems with backup/restore between PC-DOS 2.11 and 3.x.  I am one
of those priviledged people to find too late that the data is non-
restorable.  If anyone can tell me the reasoning behind the apparent
program change, please email me -- I want to know.  Anyway, there is
a very simple and (most important) cheap way of putting files backed up
on 3.x onto 2.11 DOS.  I used Turbo Pascal's BlockRead command to strip
off the first disk block, which just happens to be the entire header
(seems to me someone said that there was a header -- that is it).
Unfortunately, I don't have the source available, but the general idea
is to open the file as "file" type, read the number of blocks with
FileSize, read and discard the first block, and copy the remaining
file anywhere.  This worked great for me.  I never tried to convert
from 2.11 to 3.x, so I don't know if that would work.
