Ok then, Maurice, if you can't see the files you may have missed out one or other of the delete steps, probably the inf file (top of second column of page 66). This will then work fine with your blank card until you save a file on the 7k, see para bottom of column 2 page 66.

However with your blank 64 card it would be easier to restore the 'total contents' backup via Song Manager to your card reader as described step by step in 8.04. There is then no need to transfer to individual folders.
