Thankyou, but in the FAQ it says:
"You will need Parted >= 1.7.1 and Gtkmm >= 2.8.x
Get Parted from http://www.gnu.org/software/parted/
and Gtkmm from http://gtkmm.org/"
But these files I'm downloading seem a bit high-tech and I have no idea how to install them / use them properly before getting GParted.
On top of that, when I downloaded GParted there were no executable files, and most files had no extension at all.
