<p>I'm sure this must be possible, but I can't find out how to do it.</p>

<p>Any clues?</p>

```
```
$startinfo = new-object System.Diagnostics.ProcessStartInfo 
$startinfo.FileName = "explorer.exe"
$startinfo.WorkingDirectory = 'D:\foldername'

[System.Diagnostics.Process]::Start($startinfo)
```
```
Hope this helps
