 This container is used to proxy an existing secure smb share (version 2+) to allow legacy scanning devices, that only support cifs/smb v1 the access to a specific share or folder on the secure share - without downgrading the complete server to smb v1. Its designed to forward all files to the secure share, without overwriting files on the destination
