John,
IIRC, you are using Win7, right? You need to install a DNG codec. I don't remember which one I installed (it was many years ago). You can google it, but here are a few pointers: https://www.adobe.com/support/downloads/product.jsp?product=194&platform=Windows https://photographylife.com/how-to-view-dng-thumbnails-in-windows I actually thought I had one from MS, but it looks one doesn't exist. Also, you might find this one helpful (for non-DNG camera raw files): http://www.dpreview.com/articles/9990305507/microsoft-camera-codec-pack Igor John Sun, 19 Jun 2016 11:50:55 -0700 wrote:
I haven't figured out how to make it show thumbnails for DNG files.
