@璐村惂鐢ㄦ埛_000076K馃惥 off&title 提取指定文件夹中的前两张与最后一张图片
setlocal EnableDelayedExpansion
set lines=0
set "Path_d=%~dp0\test"
for /f "delims=" %%i in ('dir /a /b %Path_d%') do (
set /a lines+=1
if !lines! equ 1 echo;%%i
if !lines! equ 2 echo;%%i
)
for /f "delims=" %%i in ('dir /a /b /o-d %Path_d%') do (
echo;%%i
pause >nul&exit
)
自己测试过的，没问题

提一下，我这里是默认时间排序的，所以用的是/o-d，如果你是其他排序就对应一下参数

不清楚你的实际文件/情况，仅以问题中的说明及猜测为据；以下代码复制粘贴到记事本，另存为xx.bat，编码选ANSI/GB2312，跟要处理的多个文件夹放一起双击运行
<# :
cls&echo off&cd /d "%~dp0"&mode con lines=5000
