    DirectoryStream.Filter<Path> time_filter = new DirectoryStream.Filter<Path>() {

      public boolean accept(Path path) throws IOException {
        long currentTime = FileTime.fromMillis(System.currentTimeMillis()).to(
            TimeUnit.DAYS);//from  w ww. j  a v  a 2 s .c o m
        long modifiedTime = ((FileTime) Files.getAttribute(path,
