SUMMARY STEPS TO REPRODUCE 1. Put a .NRW file (RAW file from Nikon cameras) in a folder 2. Open said folder in Dolphin 3. Observe the thumbnail generated OBSERVED RESULT - No thumbnail is generated. If I rename the file to .RAW it's generated without an issue. EXPECTED RESULT - Dolphin rendering thumbnails for .NRW files SOFTWARE/OS VERSIONS Operating System: Kubuntu 19.10 KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.65.0 Qt Version: 5.12.4 Kernel Version: 5.3.0-24-generic OS Type: 64-bit Processors: 4 × Intel® Core™ i5-3210M CPU @ 2.50GHz Memory: 15.5 GiB of RAM ADDITIONAL INFORMATION Please!
Do you have kdegraphics-thumbnailers installed which contains the RAW image thumbnailer?
I have kdegraphics-thumbnailers (4:19.04.3-0ubuntu1) installed. If I change the file extension from .nrw to .raw, the thumbnail is displayed without issues.
The *.nrw extension needs to be added to the x-dcraw virtual MIME type in shared-mime-info. I suggest to request this upstream via https://www.freedesktop.org/wiki/Software/shared-mime-info/
Thank you, will do!

Alright, thanks, closing this then as it's not an issue on our side.
