Adding storage to my Fire tablet

 
I needed more storage for my smaller Fire Tablet 7 (my newer one.)

The first SD card I tried was 256GB, but resulted in a message that the disk was corrupted. I googled this issue, and learned that for some fire tablets, there's a limit to the size of the SD you can use. So I returned it and ordered a 64GB SD card.

This one also said it was corrupted. But this time I clicked on that message, and it told me I have to format it first. So it's possible the bigger SD card would have worked.

It then formatted it. 

Then it asked if I want the storage for moving files and I said no. Then it told me that if I want to use it for apps and such, that I have to move the content, so I said yes. Then it said:

 
Your SD Card is ready to uSe. Your content was moved

To manage this SanDisk SD card, go to STorage Settings.
