CloudDrive vs. Microsoft OneDrive

[RoadHazard386]

Still new to StableBit, but liking it so far. 

I've created a CloudDrive using my personal OneDrive account, and it seems to work fine. I use it as an offline backup for my various PCs. I notice that OneDrive doesn't show any of the CloudDrive files. They're all invisible. That's also fine. 

My question is, if I enable OneDrive sync on my PCs, will these invisible files sync down to my PCs, or are they somehow excluded from OneDrive sync? I hope they *don't* sync because I don't want copies of my CloudDrive files duplicated on every PC I have.
