Hi Libor,
You can take advantage of Mobile Link feature, download the Acrobat DC mobile app from Google Play or the iTunes App Store, and sign up for an Adobe Document Cloud account (if you don’t have one already). You can then enable Mobile Link in Acrobat DC on either your computer or mobile device. After you’ve opened a file on one device, you’ll see it in the recent files list on your second device. Learn more about Mobile Link.
However there is no such feature to sink the complete PC folder to document cloud.

Aadesh
