Batch file to rename "*.txt" files in the same directory according to the name of the parent directory
This batch file is placed in the same directory as the *.txt files

For a folder name like "Materials each 3", the 3 can also be greater than 10; below I use 3 as an example
".txt" becomes "---3.txt", where 3 is the number in the folder name
If already contains "---3", for example: "a---3.txt", then it does not need to be renamed; if it is "---2", then change the 2 to 3
If there are files like "a.txt" and "a---3.txt", then change "a.txt" to "a1---3.txt"; if "a1---3.txt" also exists, then keep incrementing it to "a2---3.txt". In other words, if there is a duplicate name, just vary it with a number, but the "---3" must not change.
Finally count the number of *.txt files, multiply the count by 3 to get a number N, and rename the directory to "Materials each 3---N"

=======================
Example:
Original It should become like this
a.txt a---3.txt
b.txt b---3.txt
c-----3.txt c-----3.txt (if there are more than 3 "-" symbols, it also does not need to be changed)
a a.txt a a---3.txt (there may be spaces in the filename, and there may also be Chinese characters)

d.txt d2---3.txt
d---3.txt d---3.txt
d1---3.txt d1---3.txt

e.txt e1---3.txt
e---3.txt e---3.txt
e1.txt e11---3.txt

f---2.txt f---3.txt
Finally the folder name should be changed to "Materials each 3---33", and if the batch file is run again, only the 33 should change.
=======================

This is what I wrote myself (I don't really understand it very well, I just used it as-is; I referred to the "rename" posts found by searching this site):
---------------
set a=---2
for /f "delims=" %%i in ('dir /b *.txt') do ren "%%i" "%%~ni%a%.txt"
pause
---------------
I don't know how to write the conditional checks, so after running it repeatedly, names like "a---3---3.txt" appear. That's only natural, so I'm asking everyone here to help.

Maybe what I'm asking is a bit too much, sorry. I'm also modifying the batch file and thinking it over myself.

Thanks, I'll take a look first

==========
I looked at it
Some of them say the specified file cannot be found, and repeated runs also will

I referred to the works of the veterans and improved it a little, now it can prompt for the number to input
==========
set /p a=Enter the number N to rewrite, format (for example: ---3)：
for /f "delims=" %%i in ('dir /b *.txt') do ren "%%i" "%%~ni%a%.txt"
pause
==========

Hello, using the method in your post #4, among these
=====
d.txt
e.txt
f---2.txt
=====
they can't be changed

f--2.txt, what do you want to change it to? Didn't you say that if it already is that way then it shouldn't be changed? And repeated runs shouldn't append more, right?

I tested it...

What I mean is, when I set the number to 3, I want to change the 2 to 3

Also thanks for even testing it for me, you're really a good person

My question is a bit complicated, it may be troublesome. Please take another careful look at the topic in post #1

@echo off
Set a=--5
for /f "tokens=1,2* delims=-" %%i in ('dir /b *.txt') do (
if "%%j"=="" (ren "%%i" "%%~ni%a%.txt") else (ren "%%i--%%j" "%%~ni%a%.txt")
)
pause


Only now did I notice that your j---2 has 3 of them! －

There are still problems, because the minimum number of " - " symbols has to be 3,

If there are more than 3 " - ", only change the number, for example:
c-----3, has five -, the number is correct, no change
g----2, has four -, the number is wrong, should become: g----3

If there is only one " - ", the name does not change directly; just add "---3" at the end, for example:
a-1, becomes a-1---3
b-3, becomes b-3---3

If there are two " - ", then add one more " - " symbol, for example:
e--3, becomes e---3
f--2, becomes f---3

If any of the above causes a duplicate name, then a number also needs to be added. For example:
d--2, should become d1---3
d---3, no change

!T! is the connector
!a! is the set quantity
Put it in the txt file directory and run it; repeated runs will not append more.
The number of connectors cannot be determined exactly, but it can determine more than three and less than three; basically it counts as meeting the requirements.

@echo off

setlocal enabledelayedexpansion

set T=---

set a=3

for /f "delims=" %%i in ('dir /b *.txt') do (

 for /f "tokens=1,2* delims=-" %%d in ('dir /b "%%i"') do (

  set /a n=0

  set oldn="%%i"

  set newn0=%%~nd

  set newn1="%%~nd!T!!a!.txt"

  if not !oldn!==!newn1! (

   if exist !newn1! (call :anum) else (

    ren !oldn! !newn1!

   )

  )

 )

)

goto :end

:anum

 set /a n+=1

 set newn2="!newn0!!n!!T!!a!.txt"

 if exist !newn2! (goto :anum) else (

  ren !oldn! !newn2!

 )

 goto :eof

:end

 goto :eof

It's been a long time~

Yeah, I've been working hard to learn all along. I ran into this problem again today, so I started tackling it.

OP, what are you doing this for? Could you explain?
