Copy file from PsiFile

Hi

I want to create a file on disk from an URL but I have an exception thrown, the method copyFileFrom tell me the file is non-physical and I don't know how to create a file from a resource. Can you tell me how to write that file please?

import java.net.URL;

public class CreateQueryAction extends AbstractDumbAwareAction {

    public CreateQueryAction() {
        super("Query", "Create query", PhpIcons.Php_icon);
    }

    @Override
    public void actionPerformed(@NotNull AnActionEvent e) {
        URL url = ResourceUtil.getResource(getClass(), "templates", "query.php");
        VirtualFile virtualFile = VfsUtil.findFileByURL(url);

        PsiFile file = PsiFileFactory.getInstance(e.getProject()).createFileFromText(
                virtualFile.getPath(),
                PhpFileType.INSTANCE,
                LoadTextUtil.loadText(virtualFile)
        );

        PsiDirectory directory = LangDataKeys.IDE_VIEW.getData(e.getDataContext()).getOrChooseDirectory();


        directory.copyFileFrom("query.php", file); // com.intellij.util.IncorrectOperationException: Cannot copy non-physical file: PHP file

        System.out.println("Create query");
    }
}
