Hello,
It’s a kind of a consolation to see that I’m not the only one through these issues… I did lose my files  but not the lesson 😉 
Now I’m very careful to save my work on my very computer before sending it to any cloud or box or usb key.
No more problems since then.

Now that I understood how it happenned, does anyone know why ?

Thanks for your advices.
