Question

{ 组文件1 = C：\文件路径

组文件2 = C：\文件路径

FOR％I IN（％FILE1％）DO SET DATE1 = %%〜TI \

FOR％I IN（％FILE2％）DO SET DATE2 = %%〜TI

IF “％DATE1％” GTR “％DATE2％” ECHO的文件具有相同的年龄& & GOTO END

FOR％I IN（ 'DIR/B/O：d “％FILE1％”， “％FILE2％”'）DO SET NEWEST = %%我

ECHO较新的文件 “％NEWEST％”

Answer 1

试试这个：

@echo off 
rem --compares the age of two files 
rem --by Vasil "npocmaka" Arnaudov 

call :isOlder  "C:\test.file1" "C:\test.file2" 

goto :eof 

:isOlder [%1 path to first file ; %2 path to second file] 
    setlocal 
     call :get_file_c_time "%~1" time1 
     call :get_file_c_time "%~2" time2 
    if "%time1%" LEQ "%time2%" (
      echo YES 
     ) else (
      echo NO 
     ) 
goto :eof 

:get_file_c_time [ %1 path to file; %2 variable to assign value ] 
     set file_path=%~1 

     if not exist "%file_path%" echo file %1 does not exist&& exit /b 1 

     if "%~2" equ "" echo need a secont parameter && exit /b 2 

     setlocal enableDelayedExpansion 

     for /f "skip=5 tokens=1,2,3,4,5,6 delims=/:.гчЈз " %%T in ('dir /tc "%file_path%"') do (
     if "%%Y" EQU "PM" (
      set /a "hour=%%W+12" 
     ) else (
       set hour=%%W 
     ) 
     set ftime=%%V%%U%%T!hour!%%Y 
     goto :endfor 
     ) 
:endfor 

endlocal & set "%~2=%ftime%" 
goto :eof 

这取决于时间设置，但在大多数情况下应该工作.. 另一种方法是用WMIC/WMI，但我需要一些时间来创建脚本
