In the IT industry the laplink
http://laplink.com/llgold/ is the generally excepted way to acomplish this task. Laplink Gold does not copy or move files from location to another it uses a method that is referred to as cloning. Makes little difference what format your files are in or which reader they are for Laplink clones them to the new location and your reader will not know the difference, won't know they have been moved.
