I don't really have enough info from you question to give you a perfect answer but this batch file will probably do what you need:

@echo off
:: ListAllFiles.cmd
:: Will list all files in a directory and display them or put the list of name into a file.

setlocal enableextensions

if not "%~1"=="/?" goto:nohelp

:help
echo Will place a list of all files in a directory into a file or to the screen.
echo.
echo %~n0 [/h] directory [filename]
echo.
echo        /h  List hidden files also.
echo directory  The directory to list the files from.
echo            Use a dot (.) for the current directory.
echo  filename  The filename to store the list.
echo            If no filename is given the list will be displayed on the screen.
goto:EOF

:nohelp
set _scriptname=%~n0

:: Test for /h flag.
set _dirflag=/a-d-h
if "%~1"=="/h" set _dirflag=/a-d
if "%~1"=="/H" set _dirflag=/a-d
if "%_dirflag%"=="/a-d" shift

set _directory=%~1
:: Test that the directory exists.
if exist "%_directory%\*.*" goto:directory_exists
echo The %_directory% directory does not exist.
:abort
echo %_scriptname% aborted.
goto:EOF

:directory_exists
set _filename=%~2
if "%_filename%"=="" goto:show_list
:: Test if the filename exists.
if NOT exist "%_filename%" goto:filename_new
:overwrite_ask
SET /P _answer=There is already a "%_filename%" file. Overwrite [y^|n]? 
if "%_answer%"=="y" goto:filename_delete
if "%_answer%"=="Y" goto:filename_delete
if "%_answer%"=="n" goto:abort
if "%_answer%"=="N" goto:abort
goto:overwrite_ask

:filename_delete
del "%_filename%"
if NOT exist "%_filename%" goto:filename_new
echo Unable to delete "%_filename%".
goto:abort

:filename_new
:: Ensure we can create filename.
echo.>"%_filename%"
if exist "%_filename%" goto:filename_OK
echo Unable to create "%_filename%".
goto:abort

:filename_OK
del "%_filename%"
for /f %%a in ('dir %_dirflag% /b /one "%_directory%"') do echo %%a>>"%_filename%"
echo The file %_filename% contains the list of files from "%_directory%".
goto:EOF

:show_list
echo The list of files from "%_directory%" is:
for /f %%a in ('dir %_dirflag% /b /one "%_directory%"') do echo %%a

Surprised you don't have an option or three to sort it, open it in Notepad when finished etc...

Looks impressive when you justify the 6 week project for producing a directory listing!!
