without a card reader you save the files on your pc, then transfer to the 7k and save on the sd card one by one. With a card reader it is just a lot easier using our card tool or techmanager.
Laptops and pcs are already shipped without floppy drives, my no 1 laptop has no floppy drive built in, but does have an sd drive built in. Future pcs will have flash drive bays, only complicated at the moment by too many different formats requiring several slots.
Floppies were only really necessary up to recently to boot up with no operating system. With boot cds now workable in most bios systems even that reason for floppies existence has gone.
