Hi there,
And welcome to the Q&A Board!
As far as I know you need to put the files on a computer first before they can be transferred to an iPod or player.
You can download store, and view photos, video and music on Espon Photo Storage Viewers, but they are not cheap. It allows you to backup from 18 types of memory cards and a computer isn't required.
