Die PowerShell arbeitet mit Objekten. Hier reden wir von einem System.IO.DirectoryInfo,. und wenn ich von diesem Object die
Eigenschaft Name brauche um sie in einen String zu bauen ist das die notwendige Syntax. Hier wuerde auch in dem Fall nur $Folder genuegen,
weil $folder das auswirft, wenn es in "" steht, aber das ist Objekt abhaenging, deshalb gleich die richtige Syntax nutzen.
Am besten mal damit spielen, siehe hier:
PS C:\> $folder = Get-Item F:\temp\_PS_TEST\Ordner_04
PS C:\> $folder
Verzeichnis: F:\temp\_PS_TEST
Mode LastWriteTime Length Name
---- ------------- ------ ----
d---- 31.08.2013 15:54 Ordner_04
PS C:\> "$folder"
Ordner_04
PS C:\> "$folder.name"
Ordner_04.name
PS C:\> "$($folder.name)"
Ordner_04
PS C:\> "$folder.FullName"
Ordner_04.FullName
PS C:\> "$($folder.FullName)"
F:\temp\_PS_TEST\Ordner_04
PS C:\> $Folder | Get-Member

Also es wuerde auch z.B.: folgendes gehen:
Clear-Host
$Arbeitsverzeichnis = "F:\temp\_PS_TEST"
$Flag_File = "fin"
$Folders = Get-ChildItem $Arbeitsverzeichnis | Where-Object {$_.PSisContainer}
foreach ($Folder in $Folders) {
if (Test-Path "$($Folder.FullName).$Flag_File") {
Remove-Item $Folder.FullName -Recurse -Force -WhatIf
}
}
Man koennte das ganze Problem auch noch auf andere Art und Weise loesen.
