I have a desktop running Xp SP2 and a laptop running Vista Home Premium. I want to run Xampp on an external USB hard drive. The drive will appear as F drive on both computers. This makes me believe that I should use a top level folder ie F:/Xampp on the USB drive. Is the window installer version the appropriate package to use? The whole purpose of all this is to have a local installation of my website (TNG) run from my laptop browser when I am unable to connect to the Internet.
