Organisation / Management of files on a web server

I'm looking for a good word to describe the placement of files in a 开发者_如何学Cdirectory.

For instance, putting all files that are includes within an "includes" directory.

Putting images into an "images" directory.

I'm sure there is a right word for it, its just not coming to me today :-(

I usually call this kind of information directory structure or folder structure. If you're attempting to offer a guide to best practice, you could prefix these phrases with 'suggested'...
