Usage

From source file:Main.java

public static void copyFolder(String oldPath, String newPath) {

    try {/*from w ww.  j ava  2  s. com*/
        (new File(newPath)).mkdirs();
        File a = new File(oldPath);
        String[] file = a.list();
        File temp = null;
        for (int i = 0; i < file.length; i++) {
            if (oldPath.endsWith(File.separator)) {
                temp = new File(oldPath + file[i]);
            } else {
