I prefer to shoot in RAW file format for high resolution photos. Can the unit handle these types of files?
The unit does not care which types of files you have to backup. It works with any and all types of photo or data files. Please be aware that RAW files are NOT standardized, so they do vary between camera manufacturers. Be sure to install the necessary RAW viewing software provided by your camera manufacturer to insure you are able to view them on you PC or MAC.
