用是可以用，不过在代码中使用汉字总有些问题，比如窗口要好几秒才能关闭，批处理文档格式要另存为ANSI。

哦，看错，这个只是对批处理所在目录及子目录下所有TXT删除你指定的字符
至于你说的删除备份，说明太简单，不清楚你的具体意图，不好写

@echo off
set str1=P
set str2=注
for /f "delims=" %%a in ('dir /a:-d /s /b') do (
if "%%~nxa" neq "%~nx0" (
set "file=%%a"
set "name=%%~na"
set "extension=%%~xa"
CALL set "name=%%name:%str1%=%%"
CALL set "name=%%name:%str2%=%%"
setlocal enabledelayedexpansion
ren "!file!" "!name!!extension!" 2>nul
endlocal
)

其实就在最后加一句，记得有这样有汉字的要另存ANSI编码
这个脚本可以修改当前目录以及子目录的相关文件
