Question about SANDISK Ultra Dual Drive

Yes, since the new iPad IOS, both USB sticks and external hard drives are considered external storage. So yes it works perfectly :)

Hopefully I could help you.

In principle I think you can, I just don't know exactly how the iPad will open the files on the stick. You can find information about the possible connectivity of the USB-C port on the iPad here: https://support.apple.com/fr-ch...

I hope I could help you,
