Hello,
Welcome to the forums and I used Google to translate your message. It looks like you are trying to use A360 Desktop sync component. Note that it ships with AutoCAD, AutoCAD LT, AutoCAD based verticle products and Inventor. Autodesk is getting ready to drop the A360 Desktop sync component, and so even if you installed the 2018 based products, it's not going to work. You want to check out the following link that tells you the plan for this feature and where you can get the latest version.

Hope this helps get you going and have a great day.
"Hello everybody
When I upload files to the Internet in the A360 drive, I do not see them in my Local Explorer A360 drive.
Even though I save files to my PC on my A360 drive, I do not see them on the web.
Do I have to sync somewhere?
Thank you
