List all files in an eclipse workspace recursively

The roots, projects, and folders in the workspace implement the interface IContainer.

Call IContainer.members()to get all the resources in the container.

Sort of:

void processContainer(IContainer container) throws CoreException
{
   IResource [] members = container.members();
   for (IResource member : members)
    {
       if (member instanceof IContainer)
         processContainer((IContainer)member);
       else if (member instanceof IFile)
         processFile((IFile)member);
    }
}
