Insert the SD memory card into the card adapter, and into the computer's ExpressCard port.
Open the computer's media player application from the desktop screen. (See resources section of this article if you do not have a media player application.)
Look along the left pane of the media player application and locate the SD memory card's removable device icon within the list of items. (This will be your indication that the connection has been read successfully by the computer.)
Click the "Change Sync Settings" in the removable device drop-down menu.
Click "Sync" along the media player application's menu at the top of the screen. Then, select "Library" in the same menu to view all of the media player application's library songs in the middle pane of the screen.
Browse through the library. Click a song you want to add to the SD memory card, and drag it to the "Sync" column in the right pane of the media player application. (See Tips.)
Click the "Start Sync" button at the bottom of the Sync column to begin moving the songs to the SD memory card. The application will redirect to a progress window, showing you the status of each song being added to the SD memory card.
