How can I password protect a file folder in Vista?

It was just brought to my attention that my computer had been gone through by my room mate one day when I accidentally left it on. I dont want this to happen again so I have changed my power options so that it sleeps after 1 min of no use and a password needs to be keyed in to get back into the computer. But, just in case, I would like to have a password on a few folders just to have the extra piece of mind. How can I do this the easiest?

In case you need to know:

OS = Vista Home Premium
I use “OpenOffice” for word apps.

axcrypt? I have it on xp, not sure if it’ll work for vista.

bitlocker does that I believe

Just use truecrypt dude.

Its real simple to setup a container with AES encryption, or you can encrypt the entire drive, it will ask for password at startup.

oh and break his freakin arms.

EFS

enable it. built into windows.

or hide your stuff in ADS

or just use truecrypt

use windows+L everytime you walk away

problem solved

I use Axcrypt personally and it works well for me…
