default_path = r'C:\Users\shary\Downloads' 
down_file = r'D:\Auto_folder\shary.xlsx'
list = []
listdir(default_path, list)        
new_file = newestfile(list)     
print('from:', new_file[0])
print('to:', shutil.copy(new_file[0], down_file))

將downloads目錄下的文件最新一條複製到我指定的 目錄D:\Auto_folder\

並且重命名爲：shary.xlsx
