I have a PC running Windows 8.1. When I view .orf files in File Explorer using one of the icon views, it doesn't show me the image thumbnail, instead using a generic Windows icon. I assume I need a codec for Windows that includes profiles for Olympus, but I can't find anything. When I called Microsoft support, their person couldn't find an answer and said that Olympus was responsible for providing the needed info to MS. I suspect that the support person just didn't know and couldn't find what I needed. Does anyone know what I need to make the thumbnails show up correctly in File Explorer? Thanks in advance for any help you can provide.
