PowerShell - appeler un fichier de commandes et d'attendre qu'elle se termine - Stack Overflow

I have a powershell script that could be VERY crudely represented by the following.

function startTask
{
    calls external batch script (runs for roughly 10 minutes)
    creates done1.txt
 }
function startTask2
{
    calls batch (runs for roughly 10 minutes)
    creates done2.txt
}
startTask
if done1.txt exists
startTask2
if done2.txt exists
write-host "done"

The issue I am facing is that immediately after calling the first batch file the 2nd batch file gets called. Is there a way to have powershell be aware of when the batch file is done? Side note, I don't have access to the batch file so I am unable to edit it
