Rename all TXT files in a folder using the first line of text as the filename - China DOS Union Forum

I need all TXT files in a folder to be named using the text on the first line as the filename~

Note: before the first line of text, there are many blank lines. If the blank lines can be removed, that's also fine.

Thanks to reply #2~
But~ it doesn't seem to work 'The naming syntax is incorrect'

Each of those text files has a lot of blank space at the beginning

Oh~~
Still doesn't work~
But it's much better
The renamed files don't have extensions~
And they're all the same repeated one~

Code 1:

@echo off
for %%a in (*.txt) do call :ren "%%a"
exit

:ren
for /f "tokens=*" %%a in (%~s1) do (
  ren %1 "%%a.txt"
  goto :eof
)

Code 2:

@echo off
setlocal enabledelayedexpansion
for %%a in (*.txt) do (
  set /p new<"%%a"
  ren "%%a" "!new!.txt"
)

@echo off
:: Can handle long filenames
for /f "tokens=*" %%a in ('dir/a-d/b') do (
set "a=%%a"
setlocal enabledelayedexpansion
call :sub
endlocal
)
goto :eof

:sub

::avoid itself
if "!a!"=="%~nx0" goto :eof
::the if test is to avoid lines that contain only spaces and the [TAB] key
for /f "tokens=*" %%c in ('type "!a!"') do if not "%%c"=="" (ren "!a!" "%%c"&goto :eof)

::this way can handle most special cases

Thanks. Although the text files still don't have extensions,
I have my own way to deal with it.
Problem solved.
Thank you very much~

If someone helped you solve the problem, it is recommended to do the following:

1. Modify the thread title and mark it with:

2. Add credits to the person who answered your question correctly to show your thanks. Although everyone comes to the forum to learn rather than for credits, giving credits as a token of thanks can always, to some extent, give a little comfort to the person who spent time and energy helping you selflessly.

3. If you wrote the code yourself based on someone else's hints, please post your own method and share it with everyone. Maybe others can point out shortcomings in your code, tell you how to improve execution efficiency, etc. Only through discussion can you improve faster.
