How to access LAN devices and files from iPad, iPhone? Are there any free iOS applications that let us browse LAN devices, so we could access files from devices in same network.

I use ES File Explorer to do the same in Android phone but I didn't find any free application on iOS. Most of the file explorer for android mobiles include this functionality.

Any such free app?
iFileExplorer may be what you need. It is free on App store. I am using it.
