windows - Merge 2 txt files in a single tab delimited file in batch

Question

I'm stuck with this : I need to merge two text files in a single tab delimited text file, on a batch script. ex :

file1:

qwer
tyui
asdf

file2:

1345
6876
8796

file3:

qwer    1345
tyui    6876
asdf    8796

All I need in fact, is a equivalent to Unix command : paste -d "" file1 file2 > file3

Answer 1

 @echo off

 set f1=1.txt
 set f2=2.txt
 set "sep=  "  % tab %

 (
   for /f "delims=" %%a in (%f1%) do (
      setlocal enabledelayedexpansion
       set /p line=
       echo(%%a!sep!!line!
      endlocal
   )
 )<%f2%

pause
goto :eof
