Site directory Organizing

hi i want to know is there any way to sort folders in website as i want them to be,

i want to sort these in dreamweaver and also on server.
right now my website is not live as it is in development process and it will go live on completion,

also want to tell that majority of my pages are going yo be static.

i know to place a folder on top i can add underscore as prefix but i dont want underscore to display in url so i cannot use it.

is there any way to sort folders manually
