Micro SD cards are the type of SD card you’ll usually find in your smartphone. They are also used in GPS devices and some types of cameras. If an SD card of any kind has been with you for a long enough time, you’re likely going to have to format it at some point – especially if you want to clear it. To know how to format a micro SD card and why you need to format it, read on.

There are a few different reasons why a micro SD card would need to be formatted. Formatting a micro SD card essentially resets it and wipes any information or files that are on it, giving you a blank micro SD card.

The main reason you may want to do this is if a micro SD card has stopped working properly or it has corrupted. Formatting it can sometimes save it, which in turn saves you from having to buy a new one.

Additionally, if the micro SD card is full, it is highly recommended that you format it if you want to re-use it. This will free up space and lower the chance of the micro SD card corrupting.

In this instance, only format it if you have backed up all the data on an external hard drive or to your computer.

If your micro SD card hasn’t been formatted in a while, it may be in your best interest to format it now. Regularly formatting an SD card can help its longevity and sometimes save it from corrupting prematurely.

You can format your micro SD card on your phone, but in case you use it in a camera or a GPS device too, we’ll use the computer method here:

(These can will depend on the size, age and type of SD card you use).

Make sure you have backed up any important files you wish to keep before you prgress to formatting.


Formatting a Micro SD card won’t take you very long, and lots of people think that it’s easier to do it on their smartphone. But if you just want to use the computer method, that’s fine – especially if the device the micro SD card was in isn’t a smartphone.
