How do i transfer my minecraft single player world to another PC?

I play minecraft on my work pc and I would like to work on it on my home pc. So I want to use my flash drive to copy it from one pc to the other.
I have windows 8, so that means I have to do stuff other than what it takes for windows 7.

Open up 'run' from start menu. f you don't have it, change the settings for showing 'run'
Then type in %appdata%\.minecraft\saves
each folder in the saves folder with the world name is a world save
copy the world save to cloud drive, flash stick etc.
in another computer, open up %appdata\.minecraft\saves again and copy them in.
note that minecraft can only save 5 worlds
