How to replace names recursively through a Windows batch operation

Question

I want to process a batch operation in a large directory. Actually I have a script package for this process. But here I have a problem. Some directory names, file names contain "(space). Thus, in a batch operation, these names are passed as 2 arguments. And these lines will not work. Therefore, I want to rename" "with" _ "to overcome this problem.

Example:

process / MyDirectory / Ola and Me / Private / TopSecretPictures /

this gives an error. below works fine

process / MyDirectory / Ola and Me / Private / TopSecretPictures

My goal: convert | Ola and Me | → | Ola_And_Me recursively

:)

thanks in advance.

script , , .

spaces_to_underscores.bat :

@echo off
setlocal

for /r "%~1" %%t in (.) do (
   for /f "usebackq tokens=*" %%f in (`dir /b/a-d "%%~t" 2^>nul:`) do (
      call :proc "%%~f" "%%~t"
   )
   for /f "usebackq tokens=*" %%d in (`dir /b/ad "%%~t" 2^>nul:`) do (
      call :proc "%%~d" "%%~t"
   )
)
exit /b 0

:proc
   set fn=%~1
   if "%fn: =_%"=="%fn%" exit /b 0
   set fn=%~2\%fn: =_%
   move "%~2\%~1" "%fn%" >nul:
exit /b 0

:

spaces_to_underscores "My Directory"

My Directory
    Ola and Me
        Private
            TopSecretPictures

"Ola and Me" "Ola_and_Me", , "Photo 001.jpg" "Photo_001.jpg". "My Directory" .
