 # Part three: configure directory and file level permissions over SMB

+Before you begin this article, make sure you've completed the previous article, [Assign share-level permissions to an identity](storage-files-identity-ad-ds-assign-permissions.md), to ensure that your share-level permissions are in place with Azure role-based access control (RBAC).
 
-After you assign share-level permissions with Azure role-based access control (RBAC), you must configure proper Windows ACLs at the root, directory, or file level, to take advantage of granular access control. The Azure RBAC share-level permissions act as a high-level gatekeeper that determines whether a user can access the share, while the Windows access control lists (ACLs) operate at a more granular level to control what operations the user can do at the directory or file level. Both share-level and file/directory level permissions are enforced when a user attempts to access a file/directory, so if there's a difference between either of them, only the most restrictive one will be applied. For example, if a user has read/write access at the file level, but only read at a share level, then they can only read that file. The same would be true if it was reversed: if a user had read/write access at the share-level, but only read at the file-level, they can still only read the file.
+After you assign share-level permissions, you must first connect to the Azure file share using the storage account key and then configure Windows access control lists (ACLs), also known as NTFS permissions, at the root, directory, or file level.

-Use the PowerShell script below to mount the Azure file share as drive Z: using the storage account key. The script will check to see if this storage account is accessible via TCP port 445, which is the port SMB uses. If port 445 is available, your file share will be mounted. Remember to replace the placeholder values with your own values.

 > [!NOTE]
 > You may see the **Full Control** ACL applied to a role already. This typically already offers the ability to assign permissions. However, because there are access checks at two levels (the share level and the file level), this is restricted. Only users who have the **SMB Elevated Contributor** role and create a new file or folder can assign permissions on those specific new files or folders without the use of the storage account key. All other permission assignment requires mounting the share with the storage account key first.

 If you have directories or files in on-premises file servers with Windows DACLs configured against the AD DS identities, you can copy it over to Azure Files persisting the ACLs with traditional file copy tools like Robocopy or [Azure AzCopy v 10.4+](https://github.com/Azure/azure-storage-azcopy/releases). If your directories and files are tiered to Azure Files through Azure File Sync, your ACLs are carried over and persisted in their native format.
