As far as I know, out of the 4 big VR video players 2 already support external drives over the usb-c port. Supporting FAT32, NTFS and exFAT.
It would be kind of a game changer for me and everybody else who has to travel a lot.
I can see that 4XVR Video Player supports them. I own Heresphere, but now need to buy 4XVR because it makes no sense running a 1000w gaming PC just to stream a movie to my Quest3. Much rather be able to connect my SSD.
