将特定数量的文件移动到新创建的编号文件夹中

Question

I currently have around 550 files in a folder with the same format (.csv) and same headers (all started with the letters "YL").

I wonder if there is a way to splits these files (50 files at a time) (order doesn't matter) into numbered folders? (ex. 1, 2, 3, 4, 5) And also create a subsequent folder for the leftover files?

I have found this scripts and tried to modify it for 50 files, but it looks like it only created a the first folder (subdir1)

@echo off
set /a counter=1
set /a filesperfolder=50
cd dir\dir_main

:loopstart
set dirname=subdir%counter%
md %dirname%
echo %dirname%

dir /b | findstr /v /i "subdir*"> %temp%\temp.txt && for /l %%l in (1,1,%filesperfolder%) do @for /f "tokens=1,2* delims=:" %%a in ('findstr /n /r "^" %temp%\temp.txt ^| findstr /r "^%%l:"') do @move %%b %dirname%\%%b >nul

set /a counter=%counter%+1
for /f "tokens=*" %%a in ('type %temp%\temp.txt ^| find /c /v ""') do set _filesmoved=%%a
del %temp%\temp.txt
IF %_filesmoved% LSS 50 goto done

goto loopstart

:done
cls
echo All files were moved!!
pause
exit

I disliked the script you found as it was hard to read and used a temp file to keep track of the list of files. (Also, it evidently doesn't work, so there's that.)

@echo off
SET /a cnt=50
SET /a fnum=0

FOR /F "delims=" %%f IN ('dir /b /a-d *.csv') DO (
    CALL :moveFile "%%f"
)

GOTO :end

:moveFile
    IF "%cnt%" equ "50" CALL :makeDir

    move "%~1" "%fnum%\%~1"
    SET /a cnt+=1

    GOTO :EOF

:makeDir
    SET /a fnum+=1
    mkdir %fnum%
    SET /a cnt=0

    GOTO :EOF

:end

Here is another way to do it. We test if there are still files in the directory, if there is, create a new directory and copy 50 files.

@echo off & setlocal enabledelayedexpansion
set fold_cnt=1
:test
set file_cnt=50
dir /a-d YL*.csv | findstr /IRC:"File(s)"
     if %errorlevel% equ 0 (
         mkdir !fold_cnt!
       ) else (
         goto :eof
   )
for %%i in (YL*.csv) do (
     if not !file_cnt! equ 0 (
         set /a file_cnt-=1
         move /Y "%%i" "!fold_cnt!\%%i"
      )
   )
set /a fold_cnt+=1
goto test
