		log.Fatal("Cannot create target folder")
	}
	defer os.RemoveAll(targetFolder)

	ioutil.WriteFile(filepath.Join(sourceFolder, "foo.txt"), []byte("Foo"), 0644)
	ioutil.WriteFile(filepath.Join(sourceFolder, "bar.txt"), []byte("Foo"), 0644)

	err = copy.Dir(sourceFolder, targetFolder)
	if err != nil {
		log.Fatal(err)
	}
	files, err := os.ReadDir(targetFolder)
