A:Answer Hello, Please be informed that yes, you can transfer the files from iphone to the drive and vice versa. However, if you want to transfer the files to the one drive then it should be in your host device which means iphone. If the files are in iXpand then it will not be visible in one drive to get it transferred. For any further assistance please submit a support ticket at https://support-en.wd.com/app/askweb.
