hi, I'm trying to strip out pairs of names (none defined) holding different .ext, from inside a text file
Meaning; if a name appears more then once, Then it's name will get stripped regardless its extension

: index

France.pdf
En.txt
En.pdf
En.ini
.....

-after

:New_index

France.pdf

TIA

Edit: also, if this can be written without a subroutine to make it simpler ..

This should work, but is untested. Working here as written below.

@ECHO OFF
SETLOCAL EnableDelayedExpansion
FOR /F "usebackq delims=" %%# IN ("index.txt") DO (
  SET "bMoreThanOnce="
  FOR /F "usebackq delims=" %%_ IN ("index.txt") DO (
    IF /I "%%~n_"=="%%~n#" (
      IF /I NOT "%%_"=="%%#" SET "bMoreThanOnce=Defined"
  ) )
  IF NOT DEFINED bMoreThanOnce ECHO>>"New_index.txt" %%#
)
