I don't think you can rename the files with tar. You may be thinking
of a tar archive, where you do "tar cvf filename /usr/directory". To
copy the files to floppy you use the device is place of "filename".

Others have answered this and yes it is quite possible. You can even
span multiple floppies using the "-M" option to tar. Also, someone
else mentioned that a bad sector would disallow you from reading the
floppy. While formatting the floppy can certainly be done I'd
personally just recommend using the "-W" tar option to verify it. This
just causes tar to reread what it just wrote to the floppy and compare
it to the original. It's too time consuming to do this on most tapes,
but on a floppy it doesn't take much time at all, particularly a
