You did not say what version of CodeIgniter you are running, but the helper your loading is using
CodeIgniter 3.x.x helper loading.
For CodeIgniter 4 you load helps like below.

PHP Code:

helper('date');

I believe this is a limitatiom in CIs dispatcher. What you want is a seperate folder foe additional controllers and I am not sure if CI 3 makes that possible. It should be possible fpr you to extend the CI dispatcher (assuming its a class, not sure about that) and add this functionality. It would not be a trivial thing. you would be essentially monkey pat hing CI making down the road updates much harder.

Your problem with a nothet dispatching strategy comes down to defining the actions and mapping uri to class:methods. CI does this automagically for you. So you are stuck with having an automagical dipatcher or one too general that it requires an additio al config file. It's a tough problem but can be solved with either strategy.

Just a NOTE:

You should not use F: as a drive in Windows, F: is reserved for Windows Networking!

Also if you read the XAMPP docs they recommend using XAMPP on drive C:.
