If sub-folders are authorized, they can not be displayed in the parent directory in local storage.
Sub directories appear directly in local storage.
I want the subfolders that I authorize to be displayed in the parent folder directory.
So I want the subfolder that I allow to be displayed in the parent folder in the local storage section.
If you want to manage detailed permissions within a larger folder, you have more options to use an external storage (e.g. via sftp) and then use this backend (e.g. Linux with ACL on filesystem) to define for each user what subfolders are visible and writeable.
If you now share a folder, no information about parent folders are shared, and subfolders within the shared folder are shared with the same permissions. In the enterprise version, you can perhaps work around with tagging and the file firewall.
