import java.io.File;
import org.apache.commons.io.FileUtils;

public class DirectorySizeSample {

    public static void main(String[] args) {

        // Using FileUtils.sizeOfDirectory() we can calculate
        // the size of a directory including it sub directory
        long size = FileUtils.sizeOfDirectory(new File("C:/Windows"));

        System.out.println("Size: " + size + " bytes");

    }
}

import java.io.File;

import org.apache.commons.io.FileUtils;

public class DirectorySizeSample {

public static void main(String[] args) {

// Using FileUtils.sizeOfDirectory() we can calculate
