Thank you Alex for your reply. For example I have transferred the total contents 32MB file onto a 64MB SD card but the KN7000 still says the files are empty although the SD card is said to have contents which were not there before I made the transfer. The same thing happens if I try to follow anything in 8.13. My PC says they are there and the KN7000 says they aint.
Will be away from the PC for a couple of days.
Many thanks.
