This script generates .txt caption files from .jpg file names

filename-to-txt.bat

@echo off

for %%i in (*.jpg) do (
  set filename=%%i
  set caption_filename=%%~ni.txt
  set caption=%%~ni

  setlocal EnableDelayedExpansion

  for /f "tokens=1 delims=()" %%a in ("!caption!") do (
    set caption=%%a
  )
  
  for /f "tokens=* delims=0123456789()" %%b in ("!caption!") do (
    set caption=%%b
  )

  echo !caption! > %%~ni.txt
)

In every .txt file, only 'ECHO is off.' is written, and when the file is run as an administrator, nothing happens. Where is the problem?

Same, so i wrote my own version in Python:
