Not specifically LR, but as my DNG photo are all for LR, there may be someone here who knows how to resolve the problem.
Windows 10 and LR Lightroom version: 6.14 [ 1149743 ] 

If I go to a Windows 10 folder - all of the jpeg files with have a thumbnail  (as do png, tiff etc)
Very few DNG files will have a thumbnail (usually none)

I have installed Microsoft raw image Extension .... v3 no difference
Have followed the steps to kill thumbnail cache, delete it, and restart explorer ... all jpeg thumbnails rebuild (slowly) but not DNG.
Have also followed the tip to uncheck 'always shows icons, never thumbnails'The advice is to click on teh top button 'apply to folders'  but I can't do that as that is greyed out.  (pic attached)

    Which app or exact camera model produced the DNGs?  If LR created the DNGs, which command (Convert Photo To DNG, Enhance, Photo Merge)?

    My phone creates DNG files directly  ..  my camera has to have the raw files converted and I use ADOBE DNG converter to do that.

    Just did a test and showed something I had not realised before.

    File saved to Desktop ..... and it has the correct thumbnail.

    When I move file to a sub-folder  of My_Pictures  is arrives there without a thumbnail.

     

    LR identifies the RAW file whether on desktop or in a my_pictures folder

    Noticed another anomaly .... on my phone the selection is simply to output 'RAW' files.

    They arrive on PC as filename.DNG

    I just opened file with Mediainfo and it reports it as an invalid tiff ?  (see attached)

    "could it be the folder attributes for 'My Pictures' are not optimal to allow DNG"

     

    Triple-check the File Explorer options for the folder containing the DNG, as you described in your first post (those are the right options). 

     

    Try making a test folder under Documents, setting its options to show thumbnails. Does the test folder display the DNG thumbnails?


    >Try making a test folder

    I'll try that
