How to make bat file listing with options to choose - windows

Question

I want to make a bat file that list all of the files in a specific directory, and add numbers at the beginning of the every one of the listed items. This numbers need to be a selectable options.
Example:
I have a folder with 5 files in it, aaa.exe, bbb.exe, ccc.exe, ddd.exe, eee.exe. When i run bat file i need to see
aaa.exe
bbb.exe
ccc.exe
ddd.exe
eee.exe
So now if i wana run 5-th exe i need to press 5, than press enter and that 5th exe will now start.
I allredy find how to list all of the items in folder with this code
REM -start "c:\windows\system32" notepad.exe
for /r %%i in (*) do echo %%i
pause
exit
but i can't figure out how to add numbers in front of the text and make that numbers to be a selectable options.
Edit---
Now im getting
ERROR: Duplicate choices are not allowed. running '""' is not
recognized as an internal or external command, operable program or
batch file.
when i'm trying to run this loop for a second time.
This is code that i wrote:
#ECHO OFF
setlocal enabledelayedexpansion
REM ---Prompt part
:choise
SET /P AREYOUSURE=Install programs (Y/[N])?
IF /I "%AREYOUSURE%" EQU "Y" GOTO :chooseInstall
IF /I "%AREYOUSURE%" EQU "N" GOTO :nope
REM --Cheking for Y or N
GOTO :choise
:nope
echo "Ok. Have a nice daty / night"
pause
exit
:chooseInstall
echo Wich program do you wana install ?
echo.
echo 1. 7Zip
echo 2. CPU Z
echo.
SET /P AREYOUSURE=Choosing:
IF /I "%AREYOUSURE%" EQU "1" set "pathToSoft=C:\Users\usr\Desktop\hello"
IF /I "%AREYOUSURE%" EQU "2" set "pathToSoft=C:\Users\usr\Desktop\bye"
echo.
echo.
echo %pathToSoft%
echo.
echo.
REM ---Installs
echo "Wich file to install"
cd %pathToSoft%
echo.
echo.
REM --Loops that scan files
set /A counter=0
for /R %%i in (*) do (
if not "%%~nxi" == "%~nx0" (
set /A counter+=1
echo !counter!: %%~nxi
set exe[!counter!]=%%i
set choice=!choice!!counter!
)
)
if %counter% LSS 10 (
choice /C %choice% /M "Choose: "
set EXENUM=!ERRORLEVEL!
) else set /P EXENUM="enter exe number: "
set EXECUTABLE=!exe[%EXENUM%]!
echo running %EXECUTABLE%
call "%EXECUTABLE%"
echo.
echo.
echo.
:installmore
SET /P INSTALLMORE=Do you wana install somthing else (Y/[N])?
IF /I "%INSTALLMORE%" EQU "Y" GOTO :chooseInstall
IF /I "%INSTALLMORE%" EQU "N" GOTO :nope

Answer 1

count the executables and associate them with the counter, creating kind of "array" variables (filter out the current batch script)
build the choice list at the same time
after the loop, use choice if no more than 9 choices, else use a classical interactive set
retrieve the user selection and call the executable/batch file
(you have to enable delayedexpansion to be able to use % and ! env. var separators & instant evaluation within the loop)
can be done like this:
#echo off
setlocal enabledelayedexpansion
set /A counter=0
set choice=
for /R %%i in (*) do (
if not "%%~nxi" == "%~nx0" (
set /A counter+=1
echo !counter!: %%~nxi
set exe[!counter!]=%%i
set choice=!choice!!counter!
)
)
if %counter% LSS 10 (
choice /C %choice% /M "type exe number"
set EXENUM=!ERRORLEVEL!
) else set /P EXENUM="enter exe number: "
set EXECUTABLE=!exe[%EXENUM%]!
echo running %EXECUTABLE%
call "%EXECUTABLE%"
