IWMDMStorage interface (mswmdm.h)

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. Note that storages cannot be used to refer to objects on the computer, only on the device. IWMDMStorage can contain nested objects, and can represent the root object (the entire storage medium) or any child object, such as a folder or file, on that medium. The IWMDMStorage2 interface extends this interface by making it possible to get a storage pointer from a storage name and to get and set extended attributes. IWMDMStorage3 extends this interface by supporting metadata.

To obtain a root storage object which can be queried for all other objects on a device, you must call IWMDMDevice::EnumStorage, as described in Exploring a Device.


The IWMDMStorage interface inherits from the IUnknown interface. IWMDMStorage also has these types of members:


The IWMDMStorage interface has these methods.


The EnumStorage method retrieves an IWMDMEnumStorage interface to enumerate the immediate child storages of the current storage.

The GetAttributes method retrieves the attributes of the storage.

The GetDate method retrieves the date when the storage was last modified.

The GetName method retrieves the display name of the storage.

The GetRights method retrieves rights information for a licensed storage.

The GetSize method retrieves the size of the storage, in bytes.

The GetStorageGlobals method retrieves the IWMDMStorageGlobals interface of the root storage of this storage.

The SendOpaqueCommand method sends a command to the storage through Windows Media Device Manager, without processing it.

The SetAttributes method sets the attributes of the storage.
