You can try ifunbox
How far from your home will you be able to access Splashtop and view you computer on your iPad.If you mean you want to see the computer file system, I'm afraid the only thing you'll be able to use is a remote desktop app such as Splashtop or Teamviewer (or many others). They will allow you to access and view your computer as if you we're sitting tight in front of it.
To view the iPad's file system, yeah, something like iFunbox will be good (except you won't be able to view/access everything unless the iPad is jail broken).
