Extracting files in PowerShell without third party components

Sometimes it is not acceptable to install or use third party components such as 7-zip or the PowerShell Community Extensions onto machines (particularly because they are not digitally signed). This script will extract files using the shell API:

param(
[parameter(mandatory=$true)][string]$SourceFile,
[parameter(mandatory=$true)][string]$DestinationFolder)

if(-not (test-path $DestinationFolder))
{
    md $DestinationFolder | Out-Null
}

$absoluteSource = resolve-path $SourceFile | select -ExpandProperty path
$absoluteDestination = resolve-path $DestinationFolder | select -ExpandProperty path

$app = new-object -ComObject Shell.Application
$archive = $app.Namespace($absoluteSource).Items()
$dest = $app.Namespace($absoluteDestination)
$dest.CopyHere($archive)
