Batch File Help

Hey,

I'm new to batch file programming in Windows. So I was writing this little batch file that searches for a file in a folder. What this code does is search if a file exists within the folder. Just like a dir command except it doesnt include subfolders. Is there any way I could modify this to include the subfolders????

Here's the code:

@echo off

if "%1"=="" goto error

if exist %1\nul goto folder
:0
if exist %1 goto file
:1
if exist %1.exe goto exe
:2
if exist %1.com goto com
:3
if exist %1.sys goto sys
:4
if exist %1.dll goto dll
:5
if exist %1.doc goto doc
:6
if exist %1.txt goto txt
:7
if exist %1.zip goto zip
:8
if exist %1.bmp goto bmp
:9
if exist %1.wav goto wav
:10
if exist %1.mp3 goto mp3
:11
if exist %1.jpg goto jpg
:12
if exist %1.gif goto gif
:13
if exist %1.bat goto bat

if not exist %1\nul goto a
goto exit
:a
if not exist %1 goto b
goto exit
:b
if not exist %1.exe goto c
goto exit
:c
if not exist %1.com goto d
goto exit
:d
if not exist %1.sys goto e
goto exit
:e
if not exist %1.dll goto f
goto exit
:f
if not exist %1.doc goto g
goto exit
:g
if not exist %1.txt goto h
goto exit
:h
if not exist %1.zip goto i
goto exit
:i
if not exist %1.bmp goto j
goto exit
:j
if not exist %1.wav goto k
goto exit
:k
if not exist %1.mp3 goto l
goto exit
:l
if not exist %1.jpg goto m
goto exit
:m
if not exist %1.gif goto n
goto exit
:n
if not exist %1.bat echo %1 does not exist
goto exit

:folder
echo The folder %1 exists
goto 0

:file
echo The file %1 exists.
goto 1

:exe
echo %1.exe exists
goto 2

:com
echo %1.com exists
goto 3

:sys
echo %1.sys exists
goto 4

:dll
echo %1.dll exists
goto 5

:doc
echo %1.doc exists
goto 6

:txt
echo %1.txt exists
goto 7

:zip
echo %1.sys exists
goto 8

:bmp
echo %1.bmp exists
goto 9

:wav
echo %1.wav exists
goto 10

:mp3
echo %1.mp3 exists
goto 11

:jpg
echo %1.jpg exists
goto 12

:gif
echo %1.gif exists
goto 13

:bat
echo %1.bat exists
goto exit

:error
echo usage: is filename

:exit

-----------------------------------
So thats the code. If you're new to batch files too, what u gotta do is open a text file, copy the code, and rename the text file with a .bat extension.
Then you have to use this from the command prompt.

usage: is file_name

well thats it
aye
