因为有些文件需要备份，所以就需要一个定时任务，用win10的定时任务来执行bat批处理命令是非常方便的，不用写python

@echo off  
for /f "skip=1" %%i in ('wmic os get localdatetime') do if not defined fulldate set fulldate=%%i
set year=%fulldate:~0,4%
set month=%fulldate:~4,2%
set day=%fulldate:~6,2%
set foldername=%year%.%month%.%day%
md E:\Acer\%foldername%

xcopy /e /y D:\test\te  E:\acer\%foldername%

exit 

计划任务手工运行程序，即使程序退出后还是显示“正在运行
