To ensure that a given folder exists, you can stick to trial-and-error, and hide error messages:
New-Item c:\somefolder\anotherfolder\yetanother -ItemType Directory -ea 0 | Out-Null
This will create all missing folders and hide all error messages. If you can't create the folder due to other reasons such as missing privileges, you would not get a warning, though. A more sophisticated way uses a simple condition and Test-Path:
$folder = 'C:\somefolder\anotherfolder\yetanother' if ( -not (Test-Path $folder) ) {New-Item $folder -Type Directory | Out-Null}
