The IDiskQuotaControl interface provides methods for controlling the disk quota facilities of a single NTFS volume. The client can query and set volume-specific quota attributes through IDiskQuotaControl. The client can also enumerate all per-user quota entries on the volume. A client instantiates this interface by calling the CoCreateInstance function using the class identifier CLSID_DiskQuotaControl.
