int tmp_lbl_filesize = int.Parse(gdl.GetDirectoryLength(fpath).ToString());
double tmp_lbl_filesize_db = ((double)tmp_lbl_filesize)/1048576;
string tmp_lbl = tmp_lbl_filesize_db.ToString("f2");
lbl_filesize.Text = tmp_lbl.ToString();
double tmp_lbl_leave = 100 - double.Parse(tmp_lbl);
lbl_leave.Text = tmp_lbl_leave.ToString();
