I know how to change from memory stick to phone memory for saving, in camara and video mode, but how do I change between the two for viewing purposes.?????
Actually when you are selecting a file, you will notice that there is a small memory stick icon next to it, if it is stored on the memory stick. You can use "MyPhoneExplorer" which is a nice software to copy / delete data on your phone including the memory stick
You will see image/movie files in the appropiate folder and you can just view them. They are all shown regardless of whether they are on the phone or the mem stick.
