I have a folder ABC that I’m syncing to Drive via the Drive>MyComputer>AddFolder option on Windows.

1. Is there a way to sync this ABC folder on a different PC (logged into Proton Drive as the same user) as well so it’s stored locally there and automatically syncs changes bi-directionally?

2. Can this folder show up for other Prodon Drive users as a shared folder of some kind? Or does it first have to be relocated into the Proton Drive folder to be able to do this?

3. In the original PC is there any way to make the ABC folder online-only? Or do I first have to relocate the folder to within Proton Drive in order to do this?

Also: how do I share any folder with another proton user (would be user on this same visionary plan) so that it syncs locally on their desktop?

Thanks for any help!
