        {

            DirectoryInfo[] childpath = FatherPath.GetDirectories();

            foreach (FileInfo NextFile in FatherPath.GetFiles())
                this.listBox1.Items.Add(NextFile.Name);

            if (childpath.Length != 0)
            {
                for (int i = 0; i < childpath.Length; i++)
                {
                    findallList(childpath[i]);
