Thanks for your response.
Let's have a example ..we created a shared drive and below are the two scenerio's.
1)filer level shared drive provided full control for the security group at shared drive level and at folder level, it's left as it is.
2)shared drive provided everyone full control and at folder level, security group added to the folder with full control access.
what differs in the above two scenerio's.
thanks in advance.
