问题
I want to create subdirectories and folders to organise my code in Qt.
I tried to manually create the directory in my shell / explorer, but Qt does not recognize it.

Prior to QT Creator 3.1.x, you can right-click on your project -> "add new..." and change the path to the folder you want.
Be careful the folder must exist, Qt will not create it for you.
Qt takes care of the path in your .pro file.
That's it !
