File and folder encryption methods?

[dyingcat]

Hi
I'm looking for a way to password-protect some of my files and folders. What'd be a good way to do this?

Point is, I'd like to avoid methods that require extracting the files prior using. Also, I'd like for the method to work in windows, linux and mac.

Any good tools for this?

I was looking for the same but this is only a windows utility. Just needed a simple way to protect some of my files not a huge complex thing. It's as straight forward as you can get.
