In fact I didn't find any..The only quick movements you can do are : going back to the "now playing" display and going back to the main menu. If you open the browser, you are positionned at the root of the carts, not a the current folder.
So, I'm obliged to remember the folder inside which the playing file lies, an to navigate towards it from the root of the cart.
This takes time, and also you can get lost.
I'm coming from a Cowon Z2 and a Cowon X7, where you can go back to the playing folder in just one clic, and this is very convenient.
I'm sad not to have that in the X5.
NB : I'm obliged to navigate by folders, since I have a lot of classical music, and the system o "album" "artist" is just silly for that : Have you heard of this fantastic "album" of Beethoven's ?
I need in fact a deep hierarchy of folders and sub folders named from the composers, the orchestras, the directors, the soloists, the dates of performance and so on.
So I don't tag my files, and don't use the library at all.(the good news is that I don't have to update it...)
Any views of classical music amateurs about that ?
