I bought a I USB pro file storage and file transfer USB device. does anyone have any info on this device? i’m trying to transfer files from my iphone 7 in the new files app on the phone to this IUSB PRO. I should be able to select files or bring a particular file up and on the bottom should be send to or copy to or transfer to or something but there is nothing letting me do that. anyone have one and figured it out?
