Why does the Nintendo Switch 2 not recognize my microSD Express card when first powered on?

Turn the console off/on and reinsert the card. Ensure your system has firmware 20.1.1 or later (update if needed). Check the card and slot for dirt and confirm it's a microSD Express card. If the issue persists, try formatting the card on a computer.

Will the microSD card I used in my old Nintendo Switch [1] work with the Nintendo Switch 2?

The Switch 2 requires a microSD Express card to save or run digital games. The console may be able to read screenshots and videos on a non-Express card, but you won't be able to run Switch 2 games from it.

How can I move data and games from the Nintendo Switch 2 system memory to a microSD card?

From the Home Menu, select System Settings. Scroll down and select Data Management. Select Move Data Between System/microSD Express card. Choose the software or data you want to move and select Move to microSD Express card. Confirm the action.

Why is my microSD Express card not showing its full capacity?

Flash products' capcity is often calculated using a binary algorithm, so there is a difference between usable and listed capacity. Also some capacity is used for formatting and other functions, so you can't use capacity allocated to these functions.
