I have deleted a project folder with filesystem utilities, but it is still listed in a project explorer of Eclipse Helios. How to delete project from there too?
Deletion from .metadata.plugins\org.eclipse.core.resources.projects does not help (i.e. folders are deleted from there too, but listed in project explorer nevertheless).
The solution was to “refresh” project explorer. Not sure if it is required to delete folders first, but after it was done and after refresh, Eclipse explicitly asked to remove absent projects.
