Javascript bootstrap mechanism

Hello

I am interested in finding out how the bootstrap mechanism works for sapui5 applications.

I have installed eclipse with sapui5 addons and created a simple application.

I am puzzled as to how the javascript and css files are loaded.

When I run the application in google chrome I can see that a number of files are loaded from the "resources" folder in the root directory.

But no such folder exists in my root directory.

How and where are these files being loaded from?

Thanks

Andrew
