第三行设置备份文件后缀，本批以txt为例
为保证数据安全本批只显示删除命令不执行，核对无误后把倒数第二行前面的del删除后运行即可。
@echo off
set k=3
set hz=txt
pushd r:\back
for /d %%i in (*) do (
echo %%i
for /f "skip=%k%" %%j in ('dir/b/o-d %%i\*.%hz%') do (
echo del "%%~dpnxj"))
pause
不清楚你的实际文件/情况，仅以问题中的样例/说明为据；以下代码复制粘贴到记事本，另存为xx.bat，编码选ANSI，跟要处理的文件放一起双击运行

只看修改时间吗，还是还需要看别的什么属性？
