Copy Target Of Link In Windows

How to copy the target of a link? I am using Apache's FileUtils class. I have tried the following and it only copies the link, not the target:

import org.apache.commons.io.FileUtils;
import java.io.File;
public class Copier {
public static void main(String[] args) {
File sourceFile = new File("C:/Demo/sourceDir/a_link.lnk");
File destinationDirectory = new File("C:/Demo/destinationDirectory");
FileUtils.copyFileToDirectory(sourceFile, destinationDirectory);
}
}
