I mean, you connect a phone to a USB-C Hub and the phone can gets power and the SDD /hard drives can get plugged into the USB hub, but I was wondering if there’s any apps that can sort of open up your phone’s to the internet so that you can access the files (via the phone) from another location?

I know its probably gonna be slow, but is it possible? Maybe “NAS” is the wrong term for it, I’m thinking like a personal “Cloud Drive” except I control the hardware.
