Embedded resources and clean folder structure - yes you can.

If you have a bunch of embedded resources in a folder, the single most efficient way to get a stream to them is to create a dummy class in that folder. Aside from it being internal or public, it doesn't have to do a thing.
You then use the type of this object in calls to get this resource, eg Assembly.GetManifestResourceStream. With this type, the namespace is looked up for the folder, and the embedded items in it are effortlessly resolved.
eg:
Assembly.GetExecutingAssembly().GetManifestResourceStream(typeof(ImageResourceResolver), "myicon.ico");
