这种就只能手动改了，没法用脚本偷懒
这么复杂歌名遇到的概率约等于零

可以简化成这样

这里16楼是正确答案

又发现一个问题
比如这个歌名【Mirror Mirror - M2M.mp3】
运行批处理后得到的结果是【Mirror - Mirror.mp3】
这种歌delims无法用空格做分隔符

Batcher

"tokens=1,2 delims=-. "
注意第二个双引号左边有个空格

Batcher

@echo off
for /f "delims=" %%a in ('dir /b /a-d *.mp3 ^| findstr /c:" - "') do ( 
    for /f "tokens=1,2 delims=-. " %%i in ("%%a") do (
        ren "%%a" "%%j - %%i.mp3"
    )
)
复制代码

impk

@echo off
for %%a in ( *.mp3 ) do ( 
 for /f "tokens=1,2 delims=-." %%i in ( "%%a" ) do ( ren "%%a" "%%j-%%i.mp3" )
)
pause
复制代码

参照别人的代码改了一个，文件名里多了两个空格，-的左右两边少了两个空格

@echo off
for %%a in ( *.mp3 ) do ( 
 for /f "tokens=1,2 delims=-." %%i in ( "%%a" ) do ( ren "%%a" "%%j - %%i.mp3" )
)
pause
复制代码

改成这样以后错得更离谱
