I am trying to download mp4 video files from a web browser to a formatted 128Gb usb flash drive on my 2Tb Aura. I can download them to the Download folder on the Aura's internal RAM storage successfully, but the Aura's storage is limited so I'd like to then copy them to the usb drive using the app XPlore. However, it produces an error.
I can playback pre-existing MP4 files on the usb drive (using MX Player). Are the USB sockets on the Aura read-only.
