Remove old files and empty folders

Hi,

I try to elegantely remove old files and folders.

I got this Script Snippet:

Function RemoveOldFiles
{
	$TimeSpan = "14" 
	$TargetFolder = "D:\test\folder"
	if (Test-Path $TargetFolder)
	{
		$Now = Get-Date
		$LastWrite = $Now.AddDays(-$TimeSpan)
		$Files = Get-Childitem $TargetFolder -include * -recurse | Where {$_.LastWriteTime -le "$LastWrite"} 
		foreach ($File in $Files)
		{
			write-host "Deleting file $File"; 
			Remove-Item $File | out-null
		}
	}
	else
	{
		Write-Host "'$TargetFolder' doesn't exist." -foregroundcolor "Red"
	}
}
