有大佬能帮我看一下这个把文件复制到所有用户目录下的指令可行吗

@echo off
set @=q&set/an=0x53b7e0b4
title Any question +%@%%@% %n%
cd /d "%~dp0"
set "users=%SystemDrive%\Users"
for /f "delims=" %%a in ('dir /a-d/b/s "note.txt"') do (
echo;"%%a"
for /f "delims=" %%b in ('dir /ad-h/b "%users%"') do (
echo;"%%b"
copy "%%a" "%users%\%%b\"
)
echo;-------------------
)
echo;Any question +%@%%@% %n%
pause

把二楼的代码简化了一下
注意：“所有用户目录及所有子文件夹”
我是理解为 “所有用户目录及所有用户目录的子文件夹” 的
for /r "%SystemDrive%\Users\" /d %%p in (.) do echo Copy to "%%p" & copy note.txt "%%p"

也许可以这样(有点复杂)
for %%a in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist %%a:\ echo Copy to "%%a:\" & copy note.txt %%a:\
