Instructions
Save your Wii game data to an SD (Secure Digital) card. These cards can
be bought at any electronic store and are fairly inexpensive. Move your Wii data to the card by locating your save game data and selecting the "Copy" command.
Remove your SD card from your Wii. Insert it into a suitable slot on your computer. If you don't have an SD slot on your computer, you will need to buy an SD card reader. These are inexpensive and plug in via USB. Your computer will automatically detect the SD card.
Click on the SD card prompt to open and view the files. If your computer doesn't automatically identify the SD card, go to "Computer" or "My Computer" and find your SD card. Double-click on the corresponding icon to open the file.
Right-click on the desktop. Select "New" and then select "Folder."
Left-click to select the game save files and drag the files into the new folder.
