First, marmite, I never said move the files, I said copy. Second, this is my preferred way of doing it; I am aware of the other builds though. I find this easier, as when you update your standard version, you don't need to download a second version especially for your external drive, you just copy the files as said earlier.
Of course you or the other users may chose to download the "Other Builds"; personal preference. Also there is no/little difference with either methods; aside from the memory usage of course.
