Cannot update my Air 3 no memory

[Pacefast]

I cannot upgrade my Air3 as it says not enough memory ! When I check it says 27 mbs used but in the photo folder it shows empty
I have removed the SD card reformatted and still not enough memory
Still showing 27 mbs used and still an empty folder

Do your upgrades from the assistant on your Computer.
