Besitzer von Datei ermitteln über ObjectEvent

Hallo!

Ich möchte in eine Logdatei schreiben wer welche Datei wann in einem bestimmten Verzeichnis abgelegt hat. Dazu habe ich folgendes Skript gefunden:

#By BigTeddy 05 September 2011

#This script uses the .NET FileSystemWatcher class to monitor file events in folder(s).
#The advantage of this method over using WMI eventing is that this can monitor sub-folders.
#The -Action parameter can contain any valid Powershell commands.  I have just included two for example.
#The script can be set to a wildcard filter, and IncludeSubdirectories can be changed to $true.
#You need not subscribe to all three types of event.  All three are shown for example.
# Version 1.1

$folder = 'c:\temp' # Enter the root path you want to monitor.
$filter = '*.*'  # You can enter a wildcard filter here.

# In the following line, you can change 'IncludeSubdirectories to $true if required.
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property @{IncludeSubdirectories = $false;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite, Security'}

# Here, all three events are registerd.  You need only subscribe to events that you need:

Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$name = $Event.SourceEventArgs.Name
$User = $Event.SourceEventArgs.User
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
Write-Host "The file '$name' was $changeType at $timeStamp $User" -fore green
Out-File -FilePath C:\Users\niesel\Documents\Services\outlog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"}

Register-ObjectEvent $fsw Deleted -SourceIdentifier FileDeleted -Action {
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
$User = $Event.SourceEventArgs.Username
Write-Host "The file '$name' was $changeType at $timeStamp $User" -fore red
Out-File -FilePath C:\Users\niesel\Documents\Services\outlog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"}

Register-ObjectEvent $fsw Changed -SourceIdentifier FileChanged -Action {
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
$User = $Event.SourceEventArgs.UserName
Write-Host "The file '$name' was $changeType at $timeStamp $User" -fore white
Out-File -FilePath C:\Users\niesel\Documents\Services\outlog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"}

# To stop the monitoring, run the following commands:
# Unregister-Event FileDeleted
# Unregister-Event FileCreated
# Unregister-Event FileChanged

Wie kann ich noch zusätzlich den besitzer ermitteln?
