Copy project files to a new project

[C# Programming]

I am new to C# and have been testing many features in a single project. Now that I have tested and refined what I have done I would like to "copy" the classes, forms and some other information to a new (non cluttered) project. What is the the best way of going about this. Copy the whole project folder to a new project folder and take out the things I don't need??

Thanks for you help.
