Batch file to find string in text file and if the string exists, make text file

I need a batch file to look through a text file named differance.txt. If there is a line in differance.txt that is "FC: no differences encountered" then I need to make a text file named "Downloaded.txt", if the line "FC: no differences encountered" is not in the differance.txt then I want to do nothing.
Thank you for the help,
Lori

I think this should do what you asked, let me know if you have questions.

@echo off
setlocal

REM Define files and search string
set Match=FC: no differences encountered
set SearchFile=difference.txt
set CreateFile=downloaded.txt

REM If the file to be created already exists, remove it
if exist "%CreateFile%" del "%CreateFile%" > NUL

REM If the search string is found in the file, create the new file
find /i "%Match%" "%SearchFile%" >NUL && echo.>"CreateFile"

Open in new window
