● Each USB you use is assigned its own folder. When using more than one
of the same type of USB, make sure the folders assigned to each USB
have different names.

It is recommended that you use a USB memory stick and a multi card
reader when using
with USB devices with a built-in battery, MP3 players, or PMPs made
by some manufacturers because these devices take a long time to be
recognized.
