Windows 10: DNG file not showing as Thumbnail

If I go to a folder of pictures files .... the jpeg show as thumbnails, and one or 2 DNG will show as thumbnails, but not all.If you have a great many files it is really annoying not having the thumbnail showChecked that the option in File Explore is to display as thumbnails.Followed steps to use CMD to stop & remove thumbnail cache, and then restart file explorer - no difference.Searched MS Community found this post https://answers.microsoft.com/en-us/windows/forum/all/how-to-fix-thumbnail-preview-for-dng-files-not/ed72140a-1531-4f64-8034-4a5bda451c89However when I open the 'folder optio

File Explorer not showing thumbnails

Brink,

Many thanks for you reply. I have done all the steps you suggested, but no change,

When I open a folder containing photos, some open correctly but the vast majority open with thumbnails, but they very quickly get overwritten and you can not longer see the thumbnails.

Are there any more suggestions?

 

How to Auto Rotate DNG files in Windows10

On my Windows 10 computer I can view DNG thumbnail files (with proper portrait/landscape orientation) in Explorer. When I right-click and "open with",
Photos is the only choice that will work & allow "stepping thru" to review the images full screen. However portrait images are shown as landscape. Photos
displays JPG files with proper orientation. How can I view
DNG thumbnail files with proper orientation?

 

.DNG files in Windows 10 (2018 update)

So, I'm having problems opening .DNG files from my Leica on my windows surface pro 3 running windows 10 1803. Double clicking on the file opens the Windows Photo app, and you see a brief flash of the "full size" photo then it ends up with what looks like
a low resolution thumbnail. Zooming on the final opened picture ends up with a very blurry photo.

Resetting the app (settings->apps->apps and features->advanced->reset) shows the blurry photo fit to the window (instead of a tiny thumbnail) but then when you close or double click on a .DNG again, it goes back to the previous issue, which means you see
a flash of the photo fitted to the app window, then it scales down to a thumbnail. At no point do you ever see a high resolution photo.

Opening the file (35MB) in Adobe Photoshop express or Lightroom gives you the high resolution photo.

Clearly, there's an issue with handling the .DNG file from the camera with the photo app. The only current solution is to download Adobe's DNG Converter 10.3 (available here: https://supportdownloads.adobe.com/detail.jsp?ftpID=6321) then "convert" the DNGs
to a DNG with a JPG preview, but this removes the ability to preview the photo in file explorer with the "large icons" setting. You see a regular photo file extension style icon, but if you double click, the file will come up in windows photo with a high
resolution photo.

Bottom line, how can I get *both* features? I'd like to get the preview of the photo in file explorer *and* high resolution photo in Microsoft photo. Or, should we just abandon the Microsoft photo app? Any suggestions?
