A quick way of opening PowerShell is to launch Windows Explorer, navigate to the folder with your data, then click into the navigation bar. The breadcrumb display changes and shows the folder path. Replace it with “powershell”, and press ENTER.
PowerShell opens, and the current folder is set to the folder you navigated to.
This trick does not work, though, when there is a folder called “powershell”. In this case, Explorer simply navigates to this folder.
