[tor-talk] What's written to HD?

[Dan Hughes]

Hello,

Does browsing with TBB installed on the HD or a USB stick 
and downloading files (.PDFs, S&M vids etc.;)) to a USB stick (but 
not opening online) result in the content of what's browsed or 
downloaded being written to the HD at all? 

If TBB does leave 
'content evidence' on the HD, other than Tails are there any easy ways 
(i.e. for the technically challenged) to run Tor (TBB)  from within a 
liveCD or VM to prevent this?
