1. @echo off
   
2. ::把批处理跟需处理的文件放在一起运行
   
3. setlocal enabledelayedexpansion
   
4. set olddate=%date:~,10%
   
5. for /f "delims=" %%a in ('dir /a-d /b ^|find  /i /v ".bat"') do (
   
6. set "file=%%~dpa%%a"
   
7. set "file=!file:\=\\!"
   
8. echo !file!
   
9. for /f "tokens=1* delims=. " %%b in ('wmic datafile where name^="!file!" get CreationDate ^|find "."') do set "creationdate=%%b"
   
10. set "tmpdate=!creationdate:~,4!/!creationdate:~4,2!/!creationdate:~6,2!"
    
11. set "tmptime=!creationdate:~8,2!:!creationdate:~10,2!:!creationdate:~12,2!"
    
12. date !tmpdate!
    
13. time !tmptime!
    
14. copy /b "%%a"+,, /y
    
15. )

太感谢了!!!

我看到代码后面使用了copy方法, 我不太懂啊, 不知道有没有更好的方法, copy似乎运行起来略慢了点
