With a few exceptions, all of the components, files and other resources start with "ws_". "WS" stands for Web Store, but it really is just a clever way to group all of the Shopping Cart resources within your Alpha Five project and to position those resources alphabetically close to the bottom; out of the way of the rest of your project. The few exceptions to this naming convention are A5W pages that would normally be accessed by the public, where it would look odd for them to begin with an unusual acronym.
