CMD批处理文件，如果在文本txt文件的列表中找不到文件，则删除文件

我需要一个 bat 来删除所有不包含在文本文件中的具有相对名称的文件

在文本文件 list.txt 我有这个：

C:\S-ATLANTICO-1\MEDIA\Innplay-Logo.mp4
C:\S-ATLANTICO-1\MEDIA\logo-FB_sep.png
C:\S-ATLANTICO-1\MEDIA\logo-news_sa.png

并且在同一个文件夹中有这个文件：

Innplay-Logo.mp4
logo-FB_sep.png
logo-news_sa.png
Carlos.jpg
Sapo.png
list.txt

所以我需要删除下一个文件，因为 list.txt 中不存在

Carlos.jpg
Sapo.png

但我也必须保留 LIST.TXT

我试过这个，但没有成功

@echo off
setlocal
set "folder=C:\S-ATLANTICO-1\MEDIA"
set "excludeFile=C:\S-ATLANTICO-1\MEDIA\list.txt"
for /f "eol=: delims=" %%F in ('dir /b /a-d "%folder%" ^| findstr  /vig:"%excludeFile%" ^| findstr /v /i "\list.txt"') do del "%folder%\%%F"

任何人都可以帮助我解决这个问题。

谢谢

试一试。它适用于我的测试。

我已经放置了echo语句，而不是实际删除任何内容。

@echo off
setlocal
set "folder=C:\S-ATLANTICO-1\MEDIA"
set "excludeFile=%folder%\list.txt"

:: Check that both the target folder and filter file exist before starting up.
if not exist "%folder%" echo %~nx0: The target folder doesn't exist.  Nothing to do.&& goto :EOF
if not exist "%excludeFile%" echo %~nx0: The list file doesn't exist at the location specified!&& goto :EOF

for /f "delims=" %%F in ('dir /b /a-d "%folder%"') do call :process_file "%%F" "%~0" "%excludeFile%"
goto :EOF

:: --------------------------------------------
:process_file
:: --------------------------------------------
set input_file=%~1
set this_batch=%~2
set list_file=%~nx3

:: Skip list file and this batch file too
if "%this_batch%"=="%input_file%" echo Skip this batch file&& goto :EOF
if "%list_file%"=="%input_file%" echo Skip list file&& goto :EOF

:: Grep for the include file in the list 
findstr /C:"%input_file%" "%excludeFile%" 2>&1 1>NUL

:: Bail out if the input line was in the list file
if not errorlevel 1 echo Skip "%input_file%", it is in %list_file%&& goto :EOF

:: Delete anything left
echo delete file %input_file%&& goto :EOF
goto :EOF
