     * This means that trees/sessions/connections won't be idle-disconnected even if there are no other active
     * references (currently executing code, file descriptors).
     *
     * Depending on the usage scenario, this may have some benefit as there won't be any delays for restablishing these
     * resources, however comes at the cost of having to properly release all SmbFile instances you no longer need.
