Choosing folders with numbers in batch

Question

ok so from the title you might have an idea as to what im trying to accomplish.

What I want to do is [ tree ] and show a list of folders ( hence the tree command ) and then allow me to select a folder by using numbers, the catch is that I need to be able to do so without already knowing the folder's name's

Ex. [ THIS IS WHAT I DONT WANT IT TO DO ]

cd C:\windows
tree
set input=
set /p input=Choose:
if %input%== Folder 1 goto :B
if %input%== Folder 2 goto :C
etc.

So i need it to be able to tree, set each folder as a variable and then allow me to choose that as a number some how?

Please help!

Try this Batch file, I think it is an adequate solution for this problem:

@echo off

echo Select a folder. Terminate folder number with + to open it.
echo/
call :SelectFolder selectedFolder
echo/
echo Selected folder: %selectedFolder%
goto :EOF


:SelectFolder returnVar
setlocal EnableDelayedExpansion
:nextFolder
   echo/
   echo %cd%
   set i=0
   set folder[0]=..
   echo     0- ..
   for /D %%d in (*) do (
      set /A i+=1
      set folder[!i!]=%%d
      echo     !i!- %%d
   )
   :getOption
   set option=0+
   set openFolder=1
   set /P "option=Enter the desired folder: "
   if "%option:~-1%" equ "+" (
      set option=%option:~0,-1%
   ) else (
      set openFolder=
   )
   if %option% gtr %i% goto getOption
   cd "!folder[%option%]!"
if defined openFolder goto nextFolder
endlocal & set %1=%cd%
exit /B
