routing a controller inside a folder

Hi, im migrating my app to CI 3.0 but i have a problem with something that work in CI 2, maybe the things change in new version.

I have my controllers inside a folders only one lvl for get a better organization to my project. Im not using any hmvc extension or framework to do this, ci 2.0 support one lvl of folders inside controllers and works if i put all the url in the browser but when i configure the default controller to be loaded this doesn't work.

In CI 3 it must work also .. what you have to to is to change the case of your Controller files and class names to the first Letter uppercase. Maybe this could be your problem?
