A KN2600 eh John...no floppy disk drive; only the SD Card memory facility, so you'll need to get used to transferring files direct to SD Card and its filing system. Anything from the KN2600 will NOT work in the KN7000 because all Technics are not backwards compatible - so for example a KN5000 style file would not work in a KN3000. etc etc.
That having been said it's a much lighter instrument to cart around and material on an SD Card from your KN7000 will work in the KN2600 although it might not sound exactly the same.
