For my birthday which is coming soon. I'm thinking about asking for a 32 GB SDHC Card for my Wii, 3DS, and computer. I want to put everything on my Wii SD card, my 3DS SD card, and everything on my flash drives onto this 32 GB SDHC card.
But, there's a problem with that. Is there any way that I can just take all of the data from my 2 GB SD cards for my 3DS and Wii and just put it all onto the 32 GB SD card and that the systems will recognize the data. How exactly, in great detail, are you supposed to do this?
Happy early birthday to you! First of all I advise against putting all your consoles data onto one card, because although Wii and 3DS use different sets of folder names, you might accidentally overwrite or change something when your flash drive data is in the mix. Second, should your 32GB card fail, you lose all three console data. Don't put all your eggs in one basket.
I assume you already have an SD card each for Wii and for 3DS, so keep using them. Use your 32GB for your flash drive and as a backup for your Wii and 3DS. Simply copy and paste the entire content from one card to another card.
Yeah, it's unsafe to do everything on one card, and I'd argue pretty inconvenient, and I'd also say that no one would need more than 4 GB for Wii, but if you do want to use one card, follow what this guy said about copying and pasting everything from your current cards, and be adamant in not touching the "private" and "Nintendo 3DS" folders. Those are the system ones that you shouldn't touch when using it for personal storage.
Description:Step by step instructions on how to transfer data from one SD Card to another SD Card.
Need: Two compatible SD cards or SDHC cards
Need: An SD Card slot on a PC or Mac or a commercially available SD card reader/writer
Do Not: Alter, move, or erase files in the Nintendo 3DS folder.
Do Not: Overwrite data by recopying to the same SD card.
What to do:
What I mean is, New Super Mario Bros. 2 took up 2,726 (including extra data) blocks of memory! Since the SD card started with about 15,000 blocks, that game is taking up about 1/5 of the total space that the SD Card can hold! That's about 375 megabytes! When I was trying to download New Super Mario Bros. 2 today, I didn't have enough space on the SD card, so I had to delete some things. I now have only 1,327 free blocks of memory in the SD card. If I'm going to download lots of these retail games from the eShop and make lots of videos, which also take up a lot of space (3DS videos take up WAY too much space on the SD Card.) I'm going to have to upgrade to a bigger SD card A.S.A.P.!
I wonder if I could actually use an SDXC card. According to this discussion, 3ds memory card question(s), if you format an SDXC card to FAT32, whatever the heck that is, you could use an SDXC card with the 3DS (and Wii, too?) How could you do this?
How to format SD (SDHC or SDXC) card to FAT32:
Insert the card into your USB card reader and plug the reader into your computer. If you have an internal card reader, insert the card into the reader port.
Right-click the SD card in the navigation pane on the left and choose "Format."
Make sure that the drive size option is set to the size of your card in the formatting window.
Click on the "File System" drop-down menu and change it to "FAT32."
Click on "Format" at the bottom of the window and allow the process a few minutes to complete
