How to format a MicroSD card on Windows 10
A MicroSD card belongs in small devices like phones or tablets. These devices normally do not have space for an SD card, given that the device needs to be a certain size and still pack a lot of hardware.
Outside of phones, tablets, and cameras, you won’t find a lot of devices that can read and write directly to a MicroSD card. The reason simply being that they do not have a slot small enough for it.
On devices that do have a slot for a MicroSD card, there is rarely an option to format it.
