thumbnail cache is missing

Hello everyone
I have an error on N8 that I do not have on n6.5.
The cache file of thumbnails is not created correctly and is always missing. At least in mp4, h264 and DNx.
Nobody else has this problem?

I often have this issue in 7 as well. Sometimes right click -> generate thumbnail cache helps, sometimes doesn’t

Thx but doesn’t work

If you’re always opening folders with new content in them, you generally expect Windows to take a bit of time to generate thumbnail previews for each folder because it’s looking at them for the first time.
