I realize this is an old post, but it is the most relevant to my question.
Can you confirm that the iXpand app does indeed transfer RAW image files along with JPEG files from the iOS device to the iXpand drive? It was not clear to me from this discussion that this is the case.
Like you, I transfer RAW+JPEG images from a camera SD card to an iOS device (iPad Pro) using the Apple lightning camera adapter. I want to save those RAW images to the iXpand drive while traveling when I don’t have access to the Internet or a PC.
Thanks.
