Naming convention for assets (images, css, js)?

Question

I am still struggling to find a good naming convention for assets like images, js and css files used in my web projects.

So, my current would be:

CSS:

Answer 1

/Assets/
  /Css
  /Images
  /Javascript (or Script)
    /Minified
    /Source

Is the best structure I've seen and the one I prefer. With folders you don't really need to prefix your CSS etc. with descriptive names.
