print("Switch Dir to System32 Error,check permission!npwd:"+os.getcwd())
exit()
hosts_files = glob.glob("host*")
choosed_file_idx = int(input("Choose Hosts File Index:n"+format_file_list(hosts_files)))
files_num = len(hosts_files)
if (choosed_file_idx < 0 or choosed_file_idx >= files_num) :

exit()
print("Choosed idx:{0},file:{1}.".format(choosed_file_idx,hosts_files[choosed_file_idx]))

shutil.copy(hosts_files[choosed_file_idx],"hosts")
print("Copy ok,then flush dns...")
