Share Files

How can I remotely share only one subfolder in my "Public " folder on my Network Drive.  I have tried setting up a user account for him but it won’t let me change the permissions for the public folders.  I only want him to be able to remotely access a certain “public” picture subfolder which is in the main Public folder.

You can’t manage permissions per folder, only per share.

So there is no way to only give him access to one specific subfolder?
