Welcome to AF abdamania!
Do you have a file browser such as ES File Explorer on your phone?
You can access the card and create folders with that.
If you are on your PC, can you right click to add a folder?
What errors are you getting, if any?
Can you see your sd card when plugged into the computer? Did the phone download the drivers for your phone?
I am sorry for all the questions, we just need more info to help you

Thanks for joining
