Oh, I think I got it
I shared the DCIM folder and the DCIM/Camera folder, both without any ignore rules.
On the receiver end I accepted the offer to add the DCIM older, pasted in the path of the windows folder to sync with and set up the ignore rules (anything but *.jpg and *.dng) on the windows pc(!) before saving the settings.
Then I accepted the DCIM/Camera folder to add, pasted the other windows folder and set up the ignore rules anything but *.mp4 before saving the settings.
The important part was to apply the ignore rules on the receiver side (windows pc) and not on the sharer side.
Now happily synching pictures to “pictures” and videos to “videos”
PS: It would be great if I could reuse a shared folder to sync to another location instead of having two nested shared folders which effectively share the same content.
PPS: thought again about your post sharing the same folder twice. As I’m not applying any ignore rules on the sharer side I did give it a try and it works. Now evoiding the nested folder thing, still having to create two shared folders on the sharer side, don’t I?
ignore rules used for pictures:
and for videos:
