Hey cool. I actually tried the copying but it didn't work, hence my request.
I will try it again, maybe i did something wrong.
U3 (www.u3.com) is a way of installing software to a flash/u3 stick.
Everything is run from the stick and it will leave no traces on the pc you are using.
This is great for browsing and knowing your history is not copied onto the pc.
Another thing is that no temp-files are written to the pc, so you can do your work but people can't steal it when browsing the temp-folder.

Thx again
