I have a shared folder. In this folders I have some other folders. I would set the security of these folders of 1st level to don't be deleted or renamed but I would that internally to each folder of 1st level the group of users could change, delete and rename subfolders and files.
I have tried to deflag for the group of users the option delete in the "advanced permission" of the folder of 1st level and keep flagged the option delete subfolders and files. I have tried with a login of a user and it could be possible to delete the folder of 1st level.
I have tried to deny the option delete for the group, but the user can still delete... I don't understand where i make mistake.
