thanks for your answer Michael, but that does not really answer my question.
7-zip is only part of the folder manipulation I want to do, so there is no way I can avoid running some powershell commands.
My issue is that I want the flow to continue after executing the powershell command, even if the program that is opened is still open. If I have 7 subfolders, I want the flow to run and open 7 different sessions. Right now it opens 1, and the flow continues when I close the 1st and so on
