I have a Coby MP300-4G player that I use to download my school lectures and I just cann't adjust the settings on it so when I listen to it to be able to hear the lectures in the numerical order. When I attach the player to the computer to check if the list is in numerical order it shows it the way I need it but when I listen to it and on the mp3's screen it shows in a different order. How can I change the list so that I am able to listen to the lectures in the order I need it.

Edit the filenames so that they are sequential and edit the ID3 tags as well. Do this before loading them on to the player.
