For example, under my E:\11 folder there are a lot of folders, 132132 ghsdkj hkw437....... the names have no pattern. I want to rename them according to a certain pattern, for example 001 002 003......
What should I do?
I searched the forum, and there are only ones about renaming files, none about renaming folders.

Use

ren command or move command

I of course know to use the ren command.
Help me take a look at what's wrong with what I wrote.
@echo off
dir /a /b E:\11 >1.txt
for /f %%i in (1.txt) do (for /L %%c in (1,1,20) do (ren e:\11\%%i %%c))


The first time I run it it's fine, but the next time I run it (after new folders have been added inside) it goes wrong, saying it can't find the file or that the name is duplicated.

@echo off 

set num1=0

for /f "delims=" %%i in ('dir /ad /b') do (

  set /a num1+=1

  call set num1=0000%%num1%%

  call ren "%%i" %%num1:~-3%%

  )

pause

Look at this. If the number of folders is under 1000, this will work.

If it exceeds one thousand, change call ren "%%i" %%num1:~-4%%

Set it to however many digits the quantity has.
