A文件夹里面有很多以身份证号码加随机数命名的文件现在我要匹配身份证号码的方式将对应的文件复制到桌面的目标文件夹里写出bat语句

@echo off setlocal enabledelayedexpansion

set "source_folder=C:\A文件夹" set "target_folder=C:\Users%username%\Desktop\目标文件夹"

for %%i in ("%source_folder%*") do ( set "filename=%%~ni" set "id=!filename:~0,18!" if exist "%target_folder%!id!.txt" ( copy "%%i" "%target_folder%!id!.txt" >nul echo Copied "%%~nxi" to "%target_folder%!id!.txt" ) else ( echo Cannot find matching file for "%%~nxi" ) )

echo Done. pause>nul
