I see some of my projects have 'Important Files' folder under Projects window in NetBeans. Not all projects have this. That is not a physical folder on disk either and have listing of already existing files under 'Source Files' folder. What is that and how NetBeans populates this list of files? I am using NetBeans version 7.2
Vipin:
The "nbproject" is the most important folder. If you delete this folder, and after that, you start a new project in netbeans, it's like beginning your project from zero.
