.bat file renaming folders, changing first letter of every word to uppercase

From C:\x\adrenaline_-_shut_the_fug_up_and_dance-2000

to C:\x\Adrenaline_-_Shut_The_Fug_Up_And_Dance-2000

I had this code but it capitalize every single letter instead

@echo off
setlocal disableDelayedExpansion
echo Renaming folders
for /d %%F in (C:\x\*) do (
  for /f "eol= " %%A in ("%%~nxF") do (
    set "name=%%F"
    set "newName=%%A"
    setlocal enableDelayedExpansion
    for %%C in (
        A B C D E F G H I J K L M
        N O P Q R S T U V W X Y Z
    ) do set "newName=!newName:%%C=%%C!"
    ren "!name!" "!newName!"
    endlocal
  )
)

thank you!

Solution

How about this modification? I think that this might be able to write more simpler. So please think of this as one of several answers.

Modification points :

Retrieve the initial letter from filename, and convert it to uppercase.
For each initial letter in the filename, retrieve the letter using _. And the letter of behind _ is converted to uppercase.
Add the converted letter to the filename which was removed the initial letter.
If there is the same filename, it is not renamed.

The modified script which reflected above points is as follows.

Modified script :

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
ECHO Renaming folders

SET "DIR=C:\x\"

FOR /D %%F IN (%DIR%*) DO (
  SET "BASENAME=%%~NXF"
  SET "NAME=%%~NXF"
  SET "F=TRUE"
  SET "NEWNAME="
  CALL :CONVERT
)
EXIT /B

:CONVERT
SET "L=!NAME:~0,1!"
IF %F% == TRUE (
  SET "INITIAL=!L!"
  FOR %%I IN (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) DO SET INITIAL=!INITIAL:%%I=%%I!
  SET NEWNAME=!NEWNAME!!INITIAL!
) ELSE (
  SET NEWNAME=!NEWNAME!!L!
)
IF !L! == _ (
  SET "F=TRUE"
) ELSE (
  SET "F=FALSE"
)
SET "NAME=!NAME:~1!"
IF DEFINED NAME GOTO CONVERT
IF NOT %DIR%!BASENAME! == %DIR%!NEWNAME! REN "%DIR%!BASENAME!" "!NEWNAME!"
EXIT /B

Note :

When you use this, please modify SET "DIR=C:\x\" for your environment.
Please be careful _ of the filename, because the letters for converting to the uppercase are retrieved using _.

If I misunderstand your question, I'm sorry.
