How to add existing django project to Aptana Studio 3 without modifying files?

Question

I have created a new Django project using django-admin startproject mysite on C:\tuts\ The initial file structure is as shown in the official documentation where the root folder of the project contains only one file manage.py and one folder mysite.

When I tried to create a Django project in Aptana studio 3 as follows:

File -> New -> Project... -> PyDev -> PyDev Django Project

Then after have I set Project contents to the folder C:\tuts\mysite, I had got extra files in the original project root directory.

So I need a way by which the original file structure does not be changed when I add this project to Aptana Studio 3. I'm new to Django and Python.
