Sync Across Multiple Devices

Is there a way to use it like Dropbox or Google Drive, meaning you upload from anywhere to the cloud and then it syncs automatically with all the devices that are connected to that cloud? I have installed WD Sync on every computer but I don’t know how to choose a folder from the My Cloud to download it automatically to the computer. I can only choose which folder I want to upload.

Have you looked at the User Manual for your generation of My Cloud? See Ch. 4.
