Windows Portable Devices overview
Windows Portable Devices offers you a way to manage the contents of your phone’s folders through Windows Explorer.
A phone folder is displayed for each individual phone that is connected to the PC. Phone subfolders show the applicable folders for the connected phone. In addition to the phone memory, a memory card and mass memory are shown as phone subfolders if they are available in the phone. Note that not all phone models support memory cards or mass memories.
To create a connection between your PC and the phone, see Connectivity overview.
