How to open multiple folders in a specific order using batch file? Windows 10

You can use timeout command in middle of every command. Use timeout /t 2, if you want timeout to stay quiet, timeout /t 2 >nul. It should work. Just make your code like this:

@echo off
start explorer "Folder 1 Path"
timeout /t 2 >nul
start explorer "Folder 2 Path"
timeout /t 2 >nul
start explorer "Folder 3 Path"
timeout /t 2 >nul
start explorer "Folder 4 Path"

Thanks

Using a for loop listing in order would be...

@echo off

for %%i in (
     "%UserProfile%\Desktop"
     "%UserProfile%\Documents"
     "%UserProfile%\Downloads"
     "%UserProfile%\Pictures"
    )do start "" "%%~i"
