@echo off
setlocal enabledelayedexpansion
set "aa_dir="
for %%a in (F E D C) do (
for /f "delims=" %%i in ('dir /a /b /s "%%a:\avp.exe" 2^>nul') do if not defined aa_dir set aa_dir=%%~dpi
)
start "" %aa_dir%

pause

The meaning is: First, turn off the echo of commands. Then enable delayed variable expansion. Initialize the variable aa_dir to an empty string. Then loop through drives F, E, D, C. For each drive, use the dir command to search for avp.exe in all directories and subdirectories. If aa_dir is not defined, set aa_dir to the drive and directory path where avp.exe is found. Then start the program located in aa_dir. Finally, pause to keep the window open.

Thanks. But it still doesn't work. It prompts "The system cannot find the file C:\Documents."

start "" "%aa_dir%"

The start didn't have quotes added.

This works, but it cannot solve the problem of spaces in path names.

When this code runs, it displays messages like "Device not ready" and "File not found". How to hide these messages? I added >NUL in several places and got errors.
for %%a in (Z Y X W ...

This question has been asked before.
I gave a solution at that time

Actually, it's in this format:----It can handle file names and paths with spaces

for "delims=" %%a in (xx) do ( ...... ) >nul 2>nul

...... represents all the operations you want to do, no matter how many lines or commands;

That ">nul 2>nul" must be added right after the last parenthesis ")" of for...do (...).
This can suppress any messages!

Here's an example:



@echo off



for  /f "delims=" %%i in ("%cd%") do (

echo %%i

dir c:\

dir x:\



) >nul 2>nul

This is okay, but the problem of pathname spaces cannot be solved.

You put all the displayed information into a temporary file
Hehe....

There will still be in the file!!

Solved:
1. Hide the prompt: The ">nul 2>nul" must be attached right after the last parenthesis ")" of for...do (...).
2. Space issue: According to fastslz's code, after adding the replacement character code, solve it by removing *.exe and then adding "".

Thanks to the numerous friends who replied to this post!!!

Finally, I forgot to add a "".

@echo off
setlocal enabledelayedexpansion
set "aa_dir="
for %%a in (F E D C) do (
for /f "delims=" %%i in ('dir /a /b /s "%%a:\avp.exe" 2^>nul') do if not defined aa_dir set aa_dir=%%~dpi
)
start "" "%aa_dir%"

It passed the test here
