Things You'll Need
Instructions
Turn on your Nintendo Wii and access the Data Management section of the console. From here you can add, copy, delete or otherwise update and modify the data stored on your Wii or in your SD card.
Insert your SD card into the SD card slot on the front panel of the console. Note that it is safe to attach or remove the SD card while the Wii is running.
Find and select the files in your Data Management pool that you wish to update to your SD card. This is done by highlighting the files using the directional pad or the Wiimote, and pressing A or the trigger.
Select the "Copy" command from the Data Management console, followed by the "Copy to SD Card" menu options.
Back up your Virtual Console games to your SD card to make room for new ones. Simply select them as you would any other data and copy them using the procedures above.
Save message board data to your SD card to make room for more communications. Many users send and receive messages frequently but want to save logs, so transferring them to the SD card allows you to keep logs as long as you want. The SD card will update in the order the messages were received, starting with the first.
