There isn`t any built in way to do this. I know that Samba networking does work as I used it on my old phone but it was rooted. Check this thread for info. You need to find a program that doesn`t require the device to be rooted.
If you can`t find a program that requires a root you are going to wait until the developer take a crack at the Vox and find a way to root it though. Rooting is usually pretty simple but you always have a chance of bricking yoru device when you do stuff like that.
