export all users permisions

Hi,
i want with some way to export all users permisions.
I have a file server. This file server has many many folders and subfolders.
To each folder some groups or accounts have access.
I need an export that says for example that in the folder "work" access has the folowing: "team1,team2, mmayers"

is any way to have this export???
Please help me!
Thank you in advanced
