Using Office2, you can access your iPhone or iPod Touch just like you would a network drive from either Windows Vista, Windows XP or a Mac. You can copy files to and from the device simply by dragging and dropping files from within Windows Explorer or Mac Finder. Your iPhone or iPod Touch simply needs to be available on the network via its wi-fi capability.
To copy files to and from the iPhone or iPod Touch from a desktop computer, you will need to know the connection address (or IP address) of the phone. This will vary, depending upon which network you are connected to. Provided you are successfully connected to a network, then you can find out the connection address by starting the application, pressing the Settings button (the leftmost button in the toolbar), turning on File Sharing and making a note of the address shown just under the File Sharing switch.
Once the Office2 application is started, you may connect to the phone either from a web browser, or by accessing the phone as a drive from within Windows Explorer or the Finder application (or indeed any WebDAV client).
