Transferring video to the hard drive of the hub

I have the hub, and I have been trying to figure out how to transfer media to the hard drive of the hub. As in not streaming and ONLY on the hub hard drive (I don’t have to use disc space on this computer to store it). It doesn’t transfer via USB (which is a terrible oversight), and I’m not sure what sharing does. I have managed to get sharing working, but it looks as if while sharing the media is still in the directory it was in before I set up sharing, therefore continuing to use space on my laptop and not being exclusively on the hard drive of the hub.

Geepers. When you use the hub UI, select a file you want to move. Hit the OPTION key, and select COPY. Follow the prompts.

I was moreso thinking of something a bit more automated since I have thousands of files
