I am working with the NetBeans IDE. A while ago I cleaned up the directory that holds my projects that show up in the project window of the IDE. I did this so it wouldn't take the NetBeans IDE so long to load upon startup. Well now, I would like to look back and review some of my old projects, which are now located in another directory. I copy/paste these into the correct directory and they don't show up in the Projects Window of the IDE. More recent projects in the directory show up in the Projects Window but new projects that have been copy/paste to the directory do not.
