试试这个：

@echo off & setlocal
set "MySearchString=X"
for /f "delims=" %%i in ('dir /b /s /a-d ^| findstr /i "%MySearchString%"') do echo del "%%~i"

设置变量 MySearchString 来的字符或字符串搜索和删除回声命令，如果输出OK。

Set the variable MySearchString to the character or string to search and remove the echo command, if the output is OK.

您还可以指定 MySearchString 仅文件名：

You can also specify the MySearchString for the file name only:

@echo off & setlocal
set "MySearchString=T"
for /r %%a in (*) do for /f "delims=" %%i in ('echo("%%~na" ^| findstr /i "%MySearchString%"') do echo del "%%~fa"
