How Managing NTFS

Hello everybody,
I wish you guys give me an idea about best practices NTFS.

Well I have a shared folder called USERS with full permission for a group called G_USERS.

This group has 10 G_USERS users, example:

USER_1
USER_2
USER_3
USER_4
USER_5
USER_6
USER_7
USER_8
USER_9
USER_10


My users constantly creates folder on this drive, create a folder called USER_1 FOLDER_XYZ on the server, eg:

\ \ server \ USERS \ FOLDER_XYZ

In the User folder FOLDER_XYZ USER_1 asks that only users USER_1, USER_2 USER_3 and have read and write access and other users of G_USERS group has only Read permission.

What is done?

To meet the request of the User USER_1 we created a group called G_FOLDER_XYZ_RW permission to read and write and we include the users USER_1, and USER_2 USER_3 and created a group called G_FOLDER_XYZ_R with read permission only included them and other users.

Well this way the User is happy however every time the User or another User creates a folder it asks the same thing, it creates a folder FOLDER_XPO have to create 2 groups and G_FOLDER_XPO_RW G_FOLDER_XPO_R.

Today we have 600 users and 300 groups.

Is there a way around with tools from microsoft?

Ever think of delegating this task to do however own User'm looking for something better, following the best practices.

Thanks in advance!
