How to rename the files in the path with the new names from the .txt file in batch?

Question

I have two .txt files. The first one contains the list of pathes to the CD-Images:

C:\\Users\\N\\Desktop\\LOG_Dateien_CD_Imaging\\BFU_KONGRESS_9.ISO   
C:\\Users         


        

Answer 1

you need a way to read two files in parallel:

@echo off
setlocal enabledelayedexpansion

<out.txt (
  for /f "delims=" %%a in (in.txt) do (
    set /p out=
    echo rename "%%~a" "!out!"
  )
)

Another way: read both files (one after the other) into two arrays and then work with the array variables, but it's more code and might have issues with very large files.
