This code displays messages like "Device not ready", "File not found" when running. How to hide these messages? I added >NUL in several places but got errors.

for %%a in (Z Y X W V U T S R Q P O N M L K J I H G F E D C) do for /f "delims=" %%b in ('dir /s/b/a %%a:\AVP.EXE 2^>NUL') do if exist "%%b" set xt=%%a: for /f "usebackq delims=/" %%i in (`dir /s/a-d/b %xt%\AVP.EXE 2^>NUL`) do set aa_dir=%%~dpi cd /d %aa_dir%

Thanks, please tell me where to specifically add it?

Where is the dir

It doesn't work. Can you help post the modified one? Thanks a lot.

Is your purpose to find the directory where avp.exe is located and then switch to that directory? Right?

@echo off
for %%a in (Z Y X W V U T S R Q P O N M L K J I H G F E D C) do (
dir /a /b /s "%%a:\avp.exe">nul 2>nul
if not errorlevel 1 for /f "delims=" %%i in ('dir /a /b /s "%%a:\avp.exe"') do start "" "%%~dpi"
)
pause

What does this mean?

Thanks, OK.

There is another question. Your command opens all the files found by the search. How to open only the first one found by the search?

Then find the first one, start it, and then exit.

Can GOTO be used?

Can't handle it, looking forward to a reply.

How did you write it?

:P I'm not very familiar with DOS, and I'm not familiar with some basic commands. The above code was still pieced together by searching the forum, so please give me the complete command :D
