Yes. In fact, this is a good idea. But you can’t directly copy the player’s internal memory to an external memory card inserted in the player’s card slot.
You can hook your player up to your computer, and copy the Music folder (or all the files within) to a specific place on your computer. You can create a new folder called “Player Back-Up”, “Music Back-Up” or something like that. Once copied, then put your memory card in a card reader and plug into a USB port and copy this new folder back to the card.
