and attach your images in the forum:

I reckon that 2nd policy down could have an impact, cause without any of those apps installed I mentioned, Window is in charge of making thumbs for videos. The top policy too maybe if you had ever visited the local disk location you pictured in your earlier screenshot in Explorer, cause if you had done that XY could be reading the thumbs from the Windows cache. I'd definetly try change both and restart OS,

@jupe
You were right, it was indeed the second option 'Turn off thumbnails for network drives' that was causing this. But the first option has no effect on XY, just that second one. So:

Turn off the display of thumbnails and display icons
File Explorer: Disables thumbnails on local AND network drives
XY: No effect

Turn off the display of thumbnails and display icons on network folders
File Explorer: I guess this would disable network thumbnails while enabling local thumbnails, if the first option is disabled. But I didn't bother testing with the first option disabled.
XY: Disables thumbnails in network locations

I would have never expected XY to be affected by settings for File Explorer, but I guess that shows me hah. Thanks for pointing that out to me.

@Don
Sorry about hotlinking the images, I'll make sure to attach them properly in the future.
I still think overwriting the thumbs with matching .thumb.png or .thumb.jpg would be a great option just for more control, or for when the auto-generated thumb is just not very good.

An alternative to would be a subfolder Then you won't have thumb files cluttering up your video folder.

But instead thumbs subfolders cluttering your video folders

Well, functionally (for my use case at least) it would end up the same. I can save the current frame in mpv to either the same folder, or to a thumbs folder, even if it doesn't exist. So it's still a one button thumbnail creation process. Ghost filter can hide either *.thumb.png or thumb, though is there a way to specify directory only for the latter? Wouldn't want it to match every file with 'thumb' in it.

Anyway, it should be clutter-free and functionally identical for both scenarios. I guess it comes down to either performance or preference?

Also, would it support multiple image formats? In mpv it's 10x faster to save a jpg than a png, so it makes more sense to use jpg in that case.

I'll consider it.
