You won't need a card reader, there is a cable provided in the box. You simply turn the player on then connect to your PC/laptop via USB then drag and drop your files onto the root menu of either internal or external (micro sd card). Just be sure to eject the player properly. Make sure you turn the player on before you connect to USB.
