Windows 7: Password protecting files and folders?

Is there a way to secure individual files and folders in windows so that you can then back those files up to a DVD? I encrypt certain files on my pc but as you will know if you send them to a DVD then they become un encrypted?

If it isn't possible to do it in windows does anyone know of a free 3rd party product that will do the job?

I don't need it to be military standard, cause all I need it for is to stop nosey little buggers looking at my stuff when I'm not around.

Many thanks for your help in advance.

I use AxCrypt or Truecrypt, but have never tried burning them to disc.

thanks i found it, i was asking about starting a new thread. have a good day
