Problems with copying files from list via batch file - batch-file

Question

I get a Text-file from an system - in this file there are filenames (per line one filename) - now with a batch-file every line (filename) from this list should be searched in a directory and copied in an other direcory.
I have this found and it almost works:
#echo off &setlocal
set "sourceRoot=C:\Users\test\Desktop\COPY_TEST\originale"
set "sourceList=C:\Users\test\Desktop\COPY_TEST\DBLIST.TXT"
set "destFolder=C:\Users\test\Desktop\COPY_TEST\kopiert"
for /f "delim=" %%i in ('dir /a-d /b /s "%sourceRoot%\*.pdf"^|findstr /ig:"%sourceList%"') do (
copy "%%~i" "%destFolder%\"
)
ECHO "Ausgabe abgeschlossen"
PAUSE
This works if the list looks like this:
filename1
filename2
....
BUT from the other system i get the list like this:
filename1;
filename2;
....
ANd now i have to edit the search term and add a specific term to them - original:
filename1;
But it should be searched for:
filename1_DE
So from the searchterm in the list the last character ";" should be cut and the term "_DE" should be added.
Not the list should be changed only the search term.
Is that possible?
Many thanks!

Answer 1

for /? explains expansion on variables, but in short, a file can be broken up into parts expanding on the metavariables. So as example if we have a string of a file:
D:\work\file1.txt
we can run a for loop to get the above string or parts of the string:
for %%i in (c:\work\file1.txt) do echo %%i
would echo D:\work\file1.txt
but we can now expand on %%i using things like drive, path, name, extension etc. So a straight forward example would be the below, you can copy it as is and save as a batch file and test it for yourself:
#echo off
for %%i in ("c:\work\file1.txt") do (
echo Full string and retain double quotes: %%i
echo Full string but remove double quotes: %%~i
echo Drive only: %%~di
echo Path only: %%~pi
echo Filename only: %%~ni
echo Extension only: %%~xi
echo Combination of drive and path: %%~dpi
echo Combination name and extension: %%~nxi
echo adding text between name %%~ni and extension %%~xi as: %%~niTEXT%%~xi
)
So given above explanation, you simply require using name only, add text and join with extension.
copy "%%~i" "%destFolder%\%%~ni_DE%%~xi

Thank you for your answer - i changed my version to following one and it works for me :)
#echo off &setlocal
set "sourceRoot=C:\Users\offic\Desktop\COPY_TEST\originale"
set "sourceList=C:\Users\offic\Desktop\COPY_TEST\DBLIST.TXT"
set "destFolder=C:\Users\offic\Desktop\COPY_TEST\kopiert"
set "sprache=_EN"
FOR /f "tokens=1 delims=;" %%i IN ('FINDSTR . "%sourceList%"') DO (
copy "%sourceRoot%\%%~i%sprache%.pdf" "%destFolder%\"
)
ECHO "Ausgabe abgeschlossen"
PAUSE
