I guess that is maybe what I mean. In fact, perhaps such a setting would go nicely under the startup screen section. Perhaps if it were to go there the files option should be renamed player root, and an option should be added called last working directory or something. as yes, I would like rockbox to be able to automatically place me in the last folder I was in before shutting down the player. as lets just say for example the folder you wanted was one level above the one you were in previously after shutting down the player, and you have a hard disc player, you either have to navigate through layers of folders just to get to one item, or you have to start your playlist which means a disc spinup, you then have to navigate to a given track you want to play and hit play, which means another disc spinup. I think such a feature of remembering the last folder being used would be particularly useful if you wanted to listen to a song way down the playlist as you could scroll to it, hit select once on it and therefor save yourself a disc spinup. I think this feature would be particularly useful for very complex folder structures.
Or lets say for example you are listening to audio books, and you finish a book and so that's your dynamic playlist finished, you can't resume your playlist to quickly get to the folder so you can go one level up to find another book by the same author.
