Windows Portable Devices (WPD) enables computers to communicate with attached media and storage devices.

Windows Portable Devices (WPD) enables computers to communicate with attached media and storage devices.

WPD provides a way for computers to communicate with music players, storage devices, mobile phones, cameras, and many other types of connected devices.

Applications that are built on WPD can explore a device, send and receive content, and even control the device, for example, take a picture or send a text message. The system is designed to be flexible so that many types of devices can be explored, and extensible so that driver developers can define custom properties and commands for custom devices.
