About names - please clarify

I’m still trying to get my head around how WD My Cloud integrates with Windows 10. Can somebody please explain a couple of things, in dummy-proof speak.
The WD Sync folder that you can see in Windows 10 File Explorer under “Network” is NOT actually the file/folder structure on the WD My Cloud device, it is a kind of “waiting room” for stuff that will be synced to the WD device - is that right? You could look at it as a kind of buffer where you could add 100+ files (or folders) pretty much instantly but they may not appear in the Web view (MyCloud.com) for a little while until WD Sync does its thing.
Logging into MyCloud.com (or the app) is the only way to see what has actually been successfully synced because in MyCloud.com you are looking at the actual WD My Cloud device files/folders, not the stuff in the WD Sync “Waiting Room”
That being the case, if you create a new folder in the WD Sync folder it will not appear on WD My Cloud until WD Sync is started and that folder is synced - is that all correct?
Clarification of this will help my aging brain get around all this.

Have you looked at the User Manual Chapter 4?

Hello cat0w and thanks for responding.
Yes, I do normally follow a policy of “if all else fails read the instructions” but in this case it only gave half the picture and confused me even more. I do indeed have a My Cloud folder created on my system drive as it describes in Chapter 4 but I also have diffrent stuff showing under WD My Cloud in the Network section of W10 File Explorer. There are more shares listed for example. So I’m still confused.

First, have you read the WD Sync Help?

When one typically installs WD Sync they are given the choice at one point during installation of what folders WD Sync should monitor; documents, pictures, video, music, etc. The seperate folder that is created by WD Sync on Windows (and I assume Mac) is a location where you can drag and drop files for WD Sync to copy to the My Cloud.

Not sure why you are using MyCloud.com to access the My Cloud unless you are accessing the My Cloud remotely. Normally one would use Windows File Explorer or Macintosh Finder to access the My Cloud while connected to the local network. To make things easier one can “map” the local My Cloud to their Windows/Mac computer for quick access while on the local network.
