My day job IT dept. would have a fit if that was ever brought up.
There are cloud options but that would mean a service that the school would have to pay for.
When I teach editing, all supplied files are handed on a USB drive.
They can work off the drive or leave it local it’s their choice.
But the college uses Deep Freeze so they can’t really save it on the local drive overnight.
OneDrive is buggy enough as it is, never mind as an editing portal 😛
