I have a problem with a .bat script called "ProcessMKV_EngAud_EngSub.bat" that utilizes MKVToolNix on Windows 10. This is the script:

@echo off
setlocal enabledelayedexpansion

REM ===========================
REM Configuration
REM ===========================

REM Destination directory where processed files will be saved
set "DEST_DIR=D:\Video\MKVConvert"

REM Path to the mkvmerge executable
set "MKVMERGE=C:\Program Files\MKVToolNix\mkvmerge.exe"

REM ===========================
REM Setup
REM ===========================

REM Create destination directory if it does not already exist
if not exist "%DEST_DIR%" (
mkdir "%DEST_DIR%"
)

REM ===========================
REM Processing
REM ===========================

REM Loop through each MKV file in the current directory
for %%a in (*.mkv) do (
REM Get the base name of the file without extension
set "FILE_NAME=%%~na"

REM Define the output filename
set "OUTPUT_FILE=%DEST_DIR%%%~na.mkv"

REM Check if the output file already exists
if exist "!OUTPUT_FILE!" (
echo Warning: Output file "!OUTPUT_FILE!" already exists. Skipping...
) else (
REM Display a message indicating processing
echo Processing: %%~nxa

REM Execute mkvmerge to process the file

)

)

)

REM ===========================
REM Completion Message
REM ===========================

REM Display a completion message for processing

echo All MKV files have been processed and saved in %DEST_DIR%.

REM Pause the script to allow the user to see the output
pause

Here are the files it's supposed to run through:

The Cleveland Show (2009) - S02E02 - Cleveland Live!.mkv
The Cleveland Show (2009) - S02E09 - Beer Walk!.mkv
The Cleveland Show (2009) - S03E02 - The Hurricane!.mkv
The Cleveland Show (2009) - S03E16 - Frapp Attack!.mkv
The Cleveland Show (2009) - S04E12 - Pins, Spins and Fins!.mkv
The Cleveland Show (2009) - S04E23 - Wheel! Of! Family!.mkv

Here is the output in the terminal once the script has been ran:

Processing: The Cleveland Show (2009) - S02E02 - Cleveland Live.mkv

All MKV files have been processed and saved in D:\Video\MKVConvert.
Press any key to continue . . .

However, if I remove all the exclamation points ("!") from the filename, so that the files look like this:

The Cleveland Show (2009) - S02E02 - Cleveland Live.mkv
The Cleveland Show (2009) - S02E09 - Beer Walk.mkv
The Cleveland Show (2009) - S03E02 - The Hurricane.mkv
The Cleveland Show (2009) - S03E16 - Frapp Attack.mkv
The Cleveland Show (2009) - S04E12 - Pins, Spins and Fins.mkv
The Cleveland Show (2009) - S04E23 - Wheel Of Family.mkv

Then the script has absolutely no issues at all and the output in the terminal once the script has been ran is this:

How can I fix this?
