Okay, I got the hang of it now, but had to delete both the .inf file and the .bak file to get things to work properly. Since format is easier and faster than deleting 99 folders, I suppose one has to delete the .inf file each time you start fresh. Another question, I noticed one time I had merrily gone up to 140 folders with 7 meg left on the card. The keyboard will only show the first 99 folders, but the pc shows them all which tells me the card can have folders limited only by memory space, but Technics failed to give us a page 2, page 3, etc. so we could access a 512 or larger card. That seems a tad short-sighted! Too bad there isn't some way to fool the keyboard into thinking it can read up to 999 folders. I guess I will have to be content with setting up blocks of 99 folders and simply load up what I want to use at the moment. No more questions for now, thanks for the info, guys! No more snickering either....I got this baby down!!
