Thank you all for the interesting and varied approach to my query.
(1) Settle down Elizabeth.
(2) My original curiosity was aroused because the SD card was so fast in loading, yet slow in saving.
(3)Because I have settings for nearly all songs in my commonly used books,which amount to a few hundred,songs that is,and I have to tweak all those settings from my KN5000 discs,to the Kn7, the few seconds saved each time amounts to a lot of time overall.
Also, I have access to many discs with styles and sounds, which I am saving to the
SD card for reference when I need them, and the extra time taken can be frustrating.
I agree that when closing down after use, that time can be insignificant as a one-off situation.
Isn't it strange, the older I get, the more tolerant and impatient I become.
Great to know you are all so keen to help.
Question (4) is in the pipe-line, and of a similar nature, so hone up your skills and be ready!!!!
I am also attending to big bro's questions when I can be of help to him.
