Windows File Explorer Crashes with RAF to DNG files ...

This is cross posted from the Fuji Forum ...

I just had to see what all the fuss was about and also wanted a small rangefinder style camera so, I bought a Fuji X-E3.

My version of Photoshop is too old to handle the *.RAF files from this camera (and, no, I can't update its RAW convertor as Adobe has stopped supporting it), so I downloaded the latest version of Adobe DNG Convertor (12.2) and converted my RAF files to DNG.

I have done this before, with great success, with other makes of camera. However in this case, as soon as I go to open the folder that contains the converted RAW files (RAF to DNG), Windows 10 File Explorer crashes within 5 seconds and I can not get to any of the files there-in.

Thankfully the folder in question is on an external drive. I took this drive to a Chromebook with the Android operating system and I find that I can open the folder and the files ... without anything crashing !.

So. Has anybody else had this problem and what did they do to solve it ?.

Thanks.

In summary:

This has nothing to do with Photoshop except that it will not handle my RAF files. Windows will open my RAF files so that I can VIEW them. To EDIT my files in 'RAW' I need to convert my RAF files to DNG. Photoshop will work with DNG files (it is Adobes RAW format).

Once the folder (in Windows File Explorer) containing DNG files is opened. WINDOWS 10 File Explorer becomes unstable and crashes (within approx. 5 secs) of opening the folder. This means that I cannot access ANY files in that folder (*.jpg, *.RAF or *.DNG). The folder becomes lost to me. I have tried changing the default VIEW from 'Thumbnail' to 'List' but that makes it stay open for just a little longer before it crashes.

Chromebook WILL open the folder and show me the files. I can select and see those files in Chromebook. With the folder now containing three (3) versions of the same photo (*.jpg, *.RAF and *.DNG) I can delete just the *.DNG photos then take my drive to my Windows computer and File Explorer becomes stable again but now I am back to square one where I cannot Edit my 'RAW' files !.

Also.  I have just used the same convertor to convert my Nikon D810 NEF files to DNG and Windows and Photoshop works well with the new DNG files.

Any Ideas !.

Re: Windows File Explorer Crashes with RAF to DNG files ...

1) What happens if you have only DNG files you created from the Adobe converter in a folder with no other types of files present. just DNG?

2) Have you experimented with having DNG files from other sources in a folder to see if you have the same problems? IIRC Leica, Ricoh, and DJI all natively use DNG for their RAW format so it shouldn’t be too terribly tough to find some sample files.

In the interim, you can always use the command line (DOS prompt) if you need to delete or rename files in a problematic folder. That's certainly a band-aid workaround at best but it prevents the folders from being "lost" to you.

This strikes me as likely to be an issue with the software extension that allows Windows to view the RAF files.   Windows handles DNG file types natively, but the various proprietary RAW formats require a plugin module which is normally set up when you install the manufacturer's download/image processing software.   If there's something screwy in that plugin, then it could easily cause File Explorer stability issues.

As a workaround, you could set the folder to "details" view so that it doesn't try to display thumbnails.   Then you can open the "preview" panel and click on files one at a time to show their contents in the preview window.   That might give you a better idea of exactly which file is causing the problem.
