tw other options
create a folder .... or select the files (I'd have them in one place)
right click | properties | advanced
tick encrypt. - the file folder should turn green
two drawbacks ... if your ID is logged on - the file is open by default - it's only encrypted to other IDs
the other is if you reset your password rather than changing it ... you'll loose access tio all the encrypted files
the other (and I think better) option is
truecrypt =
http://www.truecrypt.org/downloads.php
if you create an encrypted disk - you can store files in it like a secret box
you can also convert a usb stick and the software doesn't need installing ... just copy the whole folder to a usb stick and you can use it anywhere
