如何使用批处理(bat)，rar打包当前目录下的指定文件，感谢大佬！

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
cls&echo off&cd /d "%~dp0"
rem 压缩打包当前目录里的多个指定文件
set #=Any question&set _=WX&set $=Q&set/az=0x53b7e0b4
title %#% +%$%%$%/%_% %z%
set "exefile=C:\Program Files\WinRAR\WinRAR.exe"
set "newfolder=user_rar"
set files="aaa.txt" "bbbb.txt" "ccccc.txt" "ddddd.txt"
if not exist "%newfolder%" md "%newfolder%"
set "dt="&for %%a in (%files%) do (if not defined dt (set "dt=%%~ta"))
set "dt=%dt:-=%"
set "dt=%dt:/=%"
set "dt=%dt::=%"
set "dt=%dt: =_%"
set "rarfile=%newfolder%\DSFC_DSNB_%dt%.rar"
"%exefile%" a -y "%rarfile%" %files%
echo;%#% +%$%%$%/%_% %z%
pause
exit
