personal Folders for my children with unlimited access

[ludibubi]

Hi together! My name is Ludger, I come from germany and I just bought an LS520D. It's running RAID1. Now I want to create folders for my children where they can store theire pics etc..

The folders should be only accessable by them with their own password and me as the Admin. They then get a personal link for the folders, so that they can access them from their pc. If possible, they should get also an access from outside. I'm using a Fritz!Box 7590 an I have activated My!Fritz for web-access.

Now I read the manual about sharing folders. But I found only limited shares (for example tili 2022-09-22). I don't understand the manual and can't find something about unlimited access. In my company there are also folders on our NAS (Buffalo and Synology), which can used only by spedified persons.

Can someone tell me, what I must do?

Regards Ludger
