"You would be much better off converting to 7k format first and then copying, you won't have to do all the file moving on the sd card. Besides 5000 format will use up all your space unnecessarily."

I guess I didn't make myself clear, Alec. That is exactly what I do. I have to get the KN5000 file into the KN7000 before it can be converted to a KN7000 file. Once the file is in the KN7000 the most time consuming process has ended. I copy as many files as I can from a floppy. Then I edit the file name at the KN. Then I save the file to the same location as a KN7000 file removing those options like sequencer files that I don't need. Then I move the files wherever I need. The song manager is just too slow because I can only move one file at a time and the file transfer takes so long. And, unless I'm missing something, I am still limited to short file names which means that I still have to edit the file name and resave at the KN7000. I just don't follow the suggestion that the song manager would make things easier or faster. The things that I have to do at the KN7000 are still the same except for file moves.

I looked at the files with an editor and you are right. The names can be edited that way. But I don't want to confuse readers of this forum with that approach because very few of them have the knowledge to use an editor in that manner. I want to try to do this with the tools that Technics has provided.

I am not willing to risk the work I have done by doing a format and restore on my SD card until I get a second card. I'll try the backup and restore when I get the second card. I do backup the card to the laptop often as I do the file transfers. I'm not worried about the erroneous readout of space used. I'll tackle that later.
