IWMDMOperation2 The optional, application-implemented IWMDMOperation2 interface extends IWMDMOperation by providing methods to get and set extended attributes.
IWMDMOperation3 The optional, application-implemented IWMDMOperation3 interface extends IWMDMOperation by providing a new method for transferring data unencrypted for added efficiency.
IWMDMProgress The optional, application-implemented IWMDMProgress allows an application to track the progress of operations, such as formatting media or file transfers.
IWMDMProgress2 The optional, application-implemented IWMDMProgress2 interface extends the IWMDMProgress::End method by providing a status indicator.
IWMDMProgress3 The optional, application-implemented IWMDMProgress3 interface extends IWMDMProgress2 by providing additional input parameters to specify which event is being monitored, and to allow for context-specific information.Applications that implement this callback interface should provide an implementation for methods corresponding to IWMDMProgress and IWMDMProgress2 for backward compatibility, in addition to the new methods.
IWMDMRevoked The IWMDMRevoked interface retrieves the URL from which updated components can be downloaded, if a transfer fails with a revocation error.
IWMDMStorage An instance of the IWMDMStorage interface provides methods to examine and explore a storage (a generic name for a data or collection object, such as a file, folder, or playlist) on a device.
IWMDMStorage2 The IWMDMStorage2 interface extends IWMDMStorage by making it possible to get a child storage by name, and to get and set extended attributes. IWMDMStorage3 interface extends this interface by supporting metadata.
IWMDMStorage3 The IWMDMStorage3 interface extends IWMDMStorage2 by exposing metadata.
IWMDMStorage4 The IWMDMStorage4 interface extends IWMDMStorage3 by providing methods for retrieving a subset of available metadata for a storage, and for setting and retrieving a list of references to other storages.
IWMDMStorageControl The IWMDMStorageControl interface is used to insert, delete, or move files within a storage, a device, or between a device and the computer.
IWMDMStorageControl2 The IWMDMStorageControl2 interface extends IWMDMStorageControl by making it possible to set the name of the destination file when inserting content into a storage.
IWMDMStorageControl3 The IWMDMStorageControl3 interface extends IWMDMStorageControl2 by providing an Insert method that accepts an IWMDMMetaData interface pointer.
IWMDMStorageGlobals The IWMDMStorageGlobals interface provides methods for retrieving global information about a storage medium (such as a flash ROM card) on a device.

Structures

MTP_COMMAND_DATA_IN The MTP_COMMAND_DATA_IN structure contains Media Transport Protocol (MTP) custom commands that are sent to the device by using the IWMDMDevice3::DeviceIoControl method.
MTP_COMMAND_DATA_OUT The MTP_COMMAND_DATA_OUT structure contains Media Transport Protocol (MTP) responses that are filled by the device driver on exiting a call to IWMDMDevice3::DeviceIoControl.
