Your script is better than I wrote (see below) and it gives me some idea for my future scripts :-)

Thanks 😃 I specifically like using [System.IO.Path]::Combine(), I think it is the easiest to understand way to combine three or more path parts that works cross platform. Join-Path works fine for two parts of course.

(I will add the removinf of zip files after they have been unzipped).
