IWMSDataContainer Interface
The IWMSDataContainer interface represents a data container. A data container can be a file, a directory, a live stream, or some other content source. The IWMSDataContainer interface contains methods that support a data container. The methods are called by the server and implemented by a data source plug-in. The following diagram illustrates the plug-ins that work together to move content from a data source to the client.

The data source plug-in retrieves data from a source and places it into a buffer. Each type of source requires a specialized plug-in. The media parser plug-in creates a packet list of offsets into the buffer. The data sink plug-in writes the data to the client.
- Note This interface is available only on Windows Server 2003, Enterprise Edition; Windows Server 2003, Datacenter Edition; and Windows Server 2008.
In addition to the methods inherited from IUnknown, the IWMSDataContainer interface exposes the following methods.
| Method | Description |
| DoDataContainerExtendedCommand | Not implemented in this release. |
| FinishParsingPacketlist | Modifies data that is sent to a media parser after the media parser has converted it into one or more packet lists. |
| GetContainerFormat | Retrieves a GUID that identifies the format of the data container. |
| GetDataSourcePlugin | Retrieves a pointer to the data source plug-in. |
| GetInfo | Retrieves information about the data container. |
| GetTransferParameters | Retrieves the optimal offset and buffer size to use for read and write access |
| Read | Reads data from the data container. |
| Write | Writes data from a buffer to the data container. |
