On the upper status bar you have the full path, and clicking there you can browse through your folders.
I think this is what you are looking for.
Thanks sellew, your message (esp. the image) opened it up for me! It's a little scary because it seems my whole computer is suddenly on the Sony reader, but it certainly is efficient and easy.
Now, as so often in this tech stuff, there are questions that come up, which I will do another post on. Thanks again! Bear
