The IWMDMObjectInfo interface controls the way playable objects on a storage medium are referenced by the IWMDMDeviceControl interface. A playable object can be an audio file, a folder, or the root of a storage medium containing playable files.
In addition to the methods inherited from IUnknown, the IWMDMObjectInfo interface exposes the following methods.
| Method | Description |
| GetLastPlayPosition | Retrieves the previous play offset in a playable object. |
| GetLongestPlayPosition | Retrieves the longest play position of the object. |
| GetPlayLength | Retrieves the total amount of time or the time remaining that a playable object can be rendered. |
| GetPlayOffset | Retrieves the starting point for the next invocation of a play command. |
| GetTotalLength | Retrieves the total possible play length of the object in relevant units. |
| SetPlayLength | Assigns the maximum length, in relevant time units, that an object can be rendered regardless of its actual length. |
| SetPlayOffset | Assigns the offset into a playable object, in relevant units, at which audio rendering can begin. |
