Delete top level folder

Hello!

I have little question about menu. I share folder with name “films” and when i connect to this access point made by program, i see there next folder-tree:
films (Top level folder)
+FirstFolder1
++FirstFolder2
+SecondFolder2
etc.
How can i delete the top-level folder named “films”? To to see next folder-tree on connect:
FirstFolder1
+FirstFolder2
SecondFolder2

What device are you using on TV? Often the top level is dictated by the device and we can do nothing about it, hence my question.
