When my Kindle Fire HD is connected to my PC by USB cable.
I can open "Fire/ Internal Storage and I see a list of my folders on my Kindle device.
However when I open any of these folders, except Android and Image Cache, they are all empty.
Am I doing something wrong?
Can any one help, please?
Yes. LOTS wrong! First you are posting in a Kindle device forum about a Fire tablet - you should choose the Fire Tablet forum.
Secondly you are looking at the internal Android workings from a Windows PC - totally different things.
Thirdly you are looking for something that has been deliberately hidden from you by the designer.
