I am confused by your question. Did you mean, that just you as the admin, if you created 40+ personal share, one for each user that you would not like them to be visible to you? Well, first question is WHERE exactly you mean by the shares being visible? In the dashboard? In the Windows network? If so, I don’t think that you can stop from seeing all 40+ folders (in both dashboard and in the Windows network). But seeing them is one thing. Accessing them is another. If you don’t give yourself read-write access to those folders you won’t have read-write privs on them…if that is your worry.
And if you can narrow the job functions of those in your office by roles - and don’t think the workers will need to put personal sensitive stuff on the share, then you can create groups in the dashboard and add select users to groups…say Accountant Level 1, Accountant Level 2, etc. And then you can create separate shares for each of those roles (groups) and grant read-write privs to the groups accordingly. This should reduce the nuber of shares needed, assuming that you don’t have 40+ employees all unique in their role…and that there are groups of job roles.
