Hello freewaydog, welcome to Samsung Community 🙂
You can add extra space to your Galaxy Tab A by using a microSD.
Check the correct model of your Galaxy Tab A in our website, you can download the user manual and verify how to install the external memory. If you prefer, you can give us the model code of your tablet and we will be glad you help you 🙂
You can use the microSD to archive videos, pictures, music and documents.
Have a nice day!
Bye
