force building of missing thumbs and previews?

[Stephen]

I've had this problem for a long time. 82 missing thumbs are always found and rebuilt, but they do not display. Then if I repeat the process the same happens again.

I cannot find how to filter "without thumbnails", but perhaps that is only available with version 4?

Yes probably only on 4+ but click the filter Icon, then in the dropdown for the filter itself;

Thanks, so it must be a version 4 feature. I'm still using version 3.

I'm using a trial of version 4.

I can not get any of my .DNG files to show thumbnails or previews. Is this a known issue, or (more likely) am I missing something? I have even added .DNG to the "File Handling" list. This is surprising to me because even Affinity Photo files (.AFPHOTO) show with no problem. I have also tried "Build Missing Thumbnails and Previews".

Help please.

MelG,

did you check if the DNG file has the preview embedded?
When you create a DNG you need to make sure you embed the preview!
AFAIK, many of the native DNG do not have a DNG embedded...

Cheers, Michael

Thanks for the suggestion, Michael.

I do not know how to check if the preview is embedded. It does show on my system file preview (MacOS) and in the directory.
