Summary of the issue you are facing:
I try to create a folder where only one person (and the admin) has access to it.
And I need it in a particular subfolder of my external storage (a Raid1)
Further information :
So, i’m pretty new to nextcloud, I find it nice but I didn’t find how to do what I want…
Perhaps I’m overconfident but I find my demand pretty simple but it seems impossible.
So I have a Raid1 mount on the container as “External storage” excellent !
I want that because I see the Raid1 as big place to store all my data : including files, films, ect
And I need that data to be accessible by all the applications : nextcloud of course, but SFTP too, Jellyfin and other.
I already have a subfolder and want to introduce new users. Want his files at /NAS/Filer/userB
With Teams folder that is impossible because of the structure of this app. Thas create the folder on ncdata/… and not in the right place 
I’m a bit confused to not find such a good groups/users permission features to do it.
Can someone say to me if it’s a dream or if it’s possible for me to restrict a user’s rights as desired with a “normal” folder path.
And I don’t want to do it in the personal folder for the same reason, I want all files on the Raid1 and at a chosen place (To be find by other application at a same place)…
Needs are simple (I think 
) but I’m aware that surely not a simple way to do what i want.
(but the others app and my organisation need those prerequisites)
Thanks for the time you take to read me, and respond to my first question
