            System.out.println(file.getPath());
            
            boolean isfile = file.isFile();
            if (isfile) {
                System.out.println("is a file");
            } else {
                System.out.println("is not a file");
            }
            
            boolean isdirectory  = file.isDirectory ();
            if (isdirectory) {
                System.out.println("is a directory");
            } else {
