这个效率比较高

@echo off
set "folder=D:\新建文件夹 (2)"
for /f "delims=" %%i in ('type "%folder%\1.txt"') do (
  if exist "%folder%\mp3\%%i" (
    copy "%folder%\mp3\%%i" "%folder%\mp3 01\" /y
 set %%i=flag
  )
)
for /f "delims=" %%i in ('dir /b "%folder%\mp3\*.mp3"') do (
  if not defined %%i (
    copy "%folder%\mp3\%%i" "%folder%\mp3 02\" /y
    >>"%folder%\2.txt" echo %%i
  )
)
pause
