>>>>>>Hi,

And if I click on the Folder name, it won't open (showing the files). Even thought the files inside the folder Content are recognized in .cshtml files.

Yes, I realize that. But what I wanted to have - in my VS project - is the following structure:
bootstap\css -> and then files inside this folder
\js -> and then files inside this folder.

So I want to first add a folder bootstrap to my VS project, then add folder css to the folder bootstrap. But when I tried to add/create folder 'bootstrap' VS said something like 'this folder already exists'. Even though neither physical folder of this name exist. No I have (as I see it) a folder 'bootstrap' in my VS project. But I did have the folder 'bootstrap' in the project at one time.
You see what I mean?
