You can transfer Apps, Movies, Music, Photos, and Documents from Shared folders on your PC to the Kindle Fire using your Wireless LAN, without using a USB cable. Here's how:
1) Enable Network Discovery, File Sharing, and Media Sharing on your PC (Windows Vista / 7: Control Panel --> Network and Internet --> Network and Sharing Center. Once this is done, create a Shared Folder on your PC using Windows Explorer (e.g. Fire Apps). To share the Folder right click the created Folder and select Share. You can choose to share this with Everyone or just select users.
