Now there are thousands of songs, and the file names are like this:
Wang Leehom - Forever Love.mp3
Wang Leehom - I'm Lovin'it.mp3
Wan Fang - Bu Huan.mp3
Now I want to create folders respectively according to the singer names in the file names, and move the songs to the corresponding singer's directory. How to write this batch processing? Please expert teach without stint. Thanks a lot.

@echo off & setlocal EnableDelayedExpansion
set "Total=0"
for /f "delims=- tokens=1,* " %%i in (' dir /b *.mp3') do (
set /a "Total+=1"
echo 正在处理第!Total!首歌:
if not exist "%%i" md "%%i"
if exist "%%i-%%j" copy "%%i-%%j" "%cd%\%%i"
if exist "%cd%\%%i\%%i-%%j" del "%%i-%%j"
)
echo 处理完毕，共处理首歌~!&pause>nul

```
for /f "tokens=1* delims=-" %%i in ('dir/b/a-d *.mp3') do (
md %%i 2>nul&copy "%%i-%%j" %%i
)
```
It is necessary to change copy to move if needed.

Boss, the directory is there, but all the songs are gone, feeling like crying without tears.

'dir/b/a-d *.mp3'

1. I don't understand. Since it's already sorted by.mp3, what's the use of /a-d?
Does it still need to exclude the folders with *.mp3?

2. Instead of a large number of md operations, it's better to verify.

3. According to your code, the move instruction should be used instead of copy. Because you don't have the del operation.

Don't cry. Now you don't do anything.

I'll give you something.. The code was written wrong just now? But the song should have been copied to the directory, right?

I'm seeking insurance, not running on my side, it's hard to say anything. So the code you wrote may execute successfully but has problems.
1. Using.mp3 as a folder must be correct.
2. The efficiency of 2 >nul is higher than that of if exist.
3. Just what I said above.

if exist "%cd%\%%i" del "%%i-%%j"

It should be: if exist "%cd%\%%i\%%i-%%j" del "%%i-%%j"

What is your QQ number? MSN is also okay?

The directory is all set up, but all the files are gone, and the folders are all empty.

Hey. Sorry about that.

1 file(s) copied.

Is there such a prompt??

It seems that I should add if errorlevel to all code in the future

That is, there is a problem with your file name structure. It cannot have special characters, otherwise it will be empty. So that's why I used copy.

Since there are prompts? Why are all the folders empty?
