		File file = new File("c:");
    	long totalSpace = file.getTotalSpace();
    	long usableSpace = file.getUsableSpace();
    	System.out.println("Total size : " + totalSpace + " B");
    	System.out.println("Usable size : " + usableSpace + " B");

    	System.out.println("Total size : " + totalSpace/1024/1024/1024 + " GB");
    	System.out.println("Usable size : " + usableSpace/1024/1024/1024 + " GB");
    }
}
