Hi Eltopo
you are right and I created these folders in Italian while the system ones are in English. I have to say that the two languages in the OS are a bit mixed, Microsoft should be clearer in the translations.
So, I put the name of the virtual folder the same as the system one and Resilio is working linearly.
Thanks for the reply, you are kind. I think I can close the topic here if you have nothing more to add.
Greetings,
Vittorio
