I have an Android phone. Can I share files on my smartphone with all devices on the home network? Which app will let me do this?
File expert app can do this using both HTTP and FTP.
This app can share files over wifi by providing access through a browser WebSharing
Easy and simple way is just download application Wifi file Explorer which is free in android market. It enables you to connect to your phone via WiFi. The app gives you the local ip and port for your phone that you can type into your browser from your computer.
For example: if ip is 10.0.0.1 and port is 8080, write down "10.0.0.1:8080" in your browser
Then you can view your files over your wireless! And with the paid version, you can download whole folders and send files to your phone :)
