Open Folder based on project path

Hi

I would like to create a script that will open up a folder based on the projects path within the network on Windows OS.

For example - 'app.project.file.path' gives me /j/JOB/SHOT/FOLDER01/FOLDER02

Ideally I would like the script to launch a folder at the level /j/JOB/SHOT (back 2 directories)

Is there a way I can use the information from the code app.project.file.path and open the desired folder within explorer?

Many thanks
