Samba File Sharing lets you access your Android's SD card from other devices and computers on the same WiFi network as your Android. It makes your device appear as a Windows shared folder on the network. To access it, open Network (or My Network Places). You should see your Android device listed along with any other computers on the network. From there, you can connect to view and access your Android's SD storage, where you can copy/paste, drag/drop, delete, or edit files and folders.
