+ACLs let you grant "fine-grained" access, such as write access to a specific directory or file. A common ACL use case is to restrict a user's access to a specific directory without letting that user access other directories within the same container. This can be repeated for multiple users so that they each have granular access to their own directory. Without ACLs, this would require a container per local user. ACLs also make it easier for administrators to manage access for multiple local users with the help of groups. To learn more about ACLs, see [Access control lists (ACLs) in Azure Data Lake Storage](data-lake-storage-access-control.md).
 
 To authorize a local user by using ACLs, you must first enable ACL authorization for that local user. See [Give permission to containers](secure-file-transfer-protocol-support-authorize-access.md#give-permission-to-containers).
