I just use windows. When another PC come in range, it will give you the option to connect to it. Once you do, you can easily just use windows to transfer the files (I believe their computer shows up as a 'drive', but I forget since itt has been awhile since I've last used it). Eithor way, you dont need extra software.
And yes, it is a pain and not really worth it. It's slow, and the computers have to be ligned up for the connection to remain.
