is it possible to hide a local drive or network drive for other user!?
Yes. It’s possible, if you use Team Plan, mount your storage as “local drive” and not use “mount on boot”. If you use “mount on boot”, the mounted drives will be visible to other user accounts.
and what’s the different between netdrive2 and netdrive3!?
Performance has been improved, and background uploading and read-only options have been added.
There is also the ability to mount without logging in to Windows.
