A directory per project is a good rule of thumb. I generally avoid directories for file "Types", thats what file extensions are for. Also: - Adding a directory to an otherwise flat project at least 2x the complexity, so wait until there's a good reason - Every directory should have a readme. If it doesn't have a readme doesn't deserve a directory.
