How to make files private

New member here with a post setup question.  I finished my setup of my MyNet N900 and the only issue I’m having is that all my files are available to anyone who connects to the WiFi AP.  All I see available is the “Public” folder, and then all my subfolder are visible to all the mobile devices connected to the AP/SSID.  I’d like to create a “Private” folder and limit access to those files.  Is that possible??

Welcome to the community.

On the dashboard of the unit, you can change the public folder to private and it will ask you to create a username and password.

Can I make the change to private once the drive has been loaded with files?  Also, is there any way to have public and private files?  Can I make certain files public and others private via password protection or do I need to start from scratch to accomplish this?
