How can I search the local drives for the existence of a directory?

I'm trying to figure out how to determine if the directory "\Program Files (x86)\Apache Software Foundation\Apache2.2" exists on any of the local drives of a Windows 2008 machine.

I thought it'd be something like this: 

for /f "skip=2 tokens=2 delims=," %%A in (
 'wmic logicaldisk get name /format:csv'
) DO (
  echo %%A
  IF EXIST "%%A\Program Files (x86)\Apache Software Foundation\Apache2.2" (
    echo FOUND ON %%A
  )
)

But it simply echos the drive letter.

I'm a Unix guy stuck in a Windows world for this particular project, please help!

I got some help from a co-worker, here's how it was solved:

SET FOUNDIT=FALSE
SET ERRORLEVEL=

FOR /F "skip=2 tokens=2 usebackq delims=," %%i IN (
    `wmic logicaldisk where "drivetype=3" get name^,size /format:csv`
) DO (
    if /i "%foundit%" equ "true" exit /b
    CALL :APACHE %%i
    if %ERRORLEVEL% equ 0 set FOUNDIT=TRUE
)

IF %FOUNDIT% equ "TRUE" exit /B ELSE exit /B 1

:APACHE
    set DRIVE=%1
    REM echo DRIVE is %DRIVE%
    if "%DRIVE%" equ "" exit /B
    set APACHEPATH=%DRIVE%\Program Files (x86)\Apache Software Foundation\Apache2.2
    IF EXIST "%APACHEPATH%" CALL :FOUNDIT "%APACHEPATH%"

    exit /B

:FOUNDIT
    echo FOUND APACHE on %1
    for /f "tokens=*" %%x in (%1) do set APACHEINSTALLDIR=%%x
    set FOUNDIT=TRUE
    exit /B

Thanks for the help!

wmic has a ugly behaviour: it does not write proper linefeeds, so if you use the last token, you run into problems.

Workaround: don't use the last token (or force it to add another token, that you don't use, here size). As you don't use the last token, it doesn't matter that it doesn't end properly

for /F "skip=2 tokens=2 delims=," %A in ('wmic logicaldisk where "drivetype=3" get name^,size /format:csv') DO (

(you will have to escape the comma).

I added the where "drivetype=3", so it will only check HardDisks (no CD/DVD/Flash), but you can leave this out.

An another way a bit simplist but secure and much more faster as the WMIC method :

for %%a in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do (
if exist %%a: (
  IF EXIST "%%a:\Program Files (x86)\Apache Software Foundation\Apache2.2\" (
     echo FOUND ON [%%a:])))
