you're very welcome, Bob, but you also implied you had been misled.
If you ask a question, does the 7000 support long file names the answer is yes, since it does. The 7000 handles long file names to and from SD and SD backup and restore, no different to the way the hard disks operated. If you then make your own assumptions beyond the terms of the original question then those are your assumptions, not mentioned in the original question, for which you are responsible. If you ask whether floppies or the existing software handle long file names then you would receive the appropriate answers.
I think it unfair to try and imply that you were misled because you read more into an answer than what is stated on the page.
An illustration of being misled would be your own quote in the thread below "I am quite certain that the Song Manager cannot be used to drag and drop a KN5000 file from the computer to the KN7000". Since this is in fact perfectly possible, this is a statement that can unequivocally be termed as misleading since at variance with the facts.
