Calling file inside script folder in PowerShell

Question

I have a powershell script in say \Folder\ I then have an exe that I am trying to execute from \Folder\Files\

How can I execute that file without having to specify the whole path and just use either current folder then drill down to Files.

I am trying to use something like this but its not working

Start-Process -FilePath '.\Files\setup.exe' -ArgumentList "-s" -Wait

There is a difference between the working directory and the directory where the script resides. . refers to the current working directory, but you want to refer to the script directory. That question has been answered here before though (see the link in my first comment). — briantist

I actually dont want to refer to the script directory. For example here is my folder structure. Fodler1\Script.ps1 But I want to reference Folder1\Files(exefile here) — Josh D'Ambrosio

The $PSScriptRootvariable will see you right if you're using PowerShell 3 or newer. In version 2 that variable would only work within modules, and I'm not sure about version 1 (before my time.)

$PSScriptRoot gives you the path of the directory in which the script is saved (not the full path including the file name so you don't need to worry about splitting that out.)

For your specific example:

Start-Process -FilePath "$PSScriptRoot\Files\setup.exe" -ArgumentList "-s" -Wait

$PSScriptRoot was introduced with the support for modules in V2. So no, it wasn't available in V1.
