Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
There is no iPad 'Devices' menu. Go to
then go to whatever type of device you wish to change settings on or observe the status of. E.g. Bluetooth, for Bluetooth devices, Network for network devices, etc.
What device do you need to check on or change settings for? a disk device perhaps?
Folio? meaning a device? or something else?
"Folio" usually references a folding, folio-like protective case for a tablet computer.
If so, you either need
Settings - Bluetooth
Settings - Network - Wireless / WiFi.
