How do I create a Wireless File Sharing Network between a Laptop and a PC?

[tWize]

Excuse my naivety. I’ve been trying to source an answer for my dilemma on the www. but no proper clarity has been provided.

In all, I have one laptop which I use constantly use and one PC which I use only sporadically, both of which are wirelessly connected to a BT Broadband connection through the standard BT Home Hub.

Recently I have filled the space available on my laptop hard-drive and rather than looking for a new c-drive/external hard drive I am looking to create a wireless network whereby I can store all the data I don’t really use on my PC but still view, edit or manipulate it through my laptop when necessary.

As I mentioned, I have scoured the internet and found no clear answers or explanations, so a simple-all-area-covering solution would be fantastic.

Thanks. t.
