I implement Filr for management and teachers departments.

Now I want to give access to students but in tests I did, students see all
documents in teachers folders.

I explain:

Teachers have their home folder (X:\<teacher>). In that folder, their have
a Public folder (X:\<teacher>\Public) where they place files to share with
students. Students have special authorizations on the teachers root folder
to be able to navigate the folder and to see the Public folder. They have
Read permission on the Public folder. In Windows, students are seeing the
teacher root folder and only see the Public folder and it's content.

If I do a test in Filr, students are seeing teachers root folder and all the
content (files and folders) under that folder but I want users to see only
the Public folder.

Why the see all the content ? Does Filr unable to

Can somebody help me ?
