You can use a bat/cmd file with a c# code.
Then you will compile it and run it at run time to get all the strings in one line ...
1) Edit: cd /d "D:\Path\to\file\", adding the drive:\and\path\to\your\directory
2) Save this code below as File OneLine.cmd
/* 2>nul & @cls & @echo off & title <nul & title %~nx0 & setlocal enabledelayedexpansion
cd /d "D:\Path\to\file\" && set "_b64_file=%__CD__%\B64.txt"
"%__APPDIR__%certutil.exe" -encode -f ".\sample.pdf" "!_b64_file!" >nul

- Same code in conventional formatting/layout

File Class
SubString/Remove Characters in String
Get System Environment Variable string
Environment.GetEnvironmentVariable Method
Understanding the maximum character limit in the variable length, it is not possible to do it beyond 8191 digits/characters
For remove lines you can use only certificate, because this word is present in 1st and last line.
certutil + -f for overwrite file out if exist
type B64.txt^|"%__APPDIR__%find.exe" /v "CERTIFICATE" will ignore the 1st and last line
set "_b64=!_b64!%%~b" will save line by line in the same variable/1 line
>B64.txt echo/!_b64! will replace/overwrite the contents of the file with the value saved in the variable (b64 strings on one line)
