Ich weiß, dass beim Zippen von Dateien mit Powershell viel geübt wurde, aber ich finde keine Methode, die genau das tut, was ich brauche.Powershell Zip-Ordner Inhalt
Ich möchte Ordner UND Dateien in einem ZIP-Ordner komprimieren können, ohne den übergeordneten Ordner in der ZIP. So habe ich zum Beispiel einen Ordner namens STUFF, der Dateien/Ordner enthält, den ich in einen Ordner namens STUFF.zip zippen möchte. Diese Ordner-Struktur wäre dann STUFF.zip> Dateien/Ordner NICHT STUFF.zip> STUFF> Dateien/Ordner, wie ich zur Zeit dieses Code erhalten mit ...

kompletter Kredit geht für diesen Code here. Ich schätze jede Hilfe, die ich bekomme, diese Fähigkeit ist entscheidend für mein Projekt! Leider kann ich das Community Extension-Modul nicht verwenden, da andere PCs, auf denen dieses Programm ausgeführt wird, dieses Modul nicht installiert haben.
Danke!
Dotnet 4.5 hinzugefügt Zip-Funktionalität, die Ihnen bessere Optionen als die COM-Methoden geben sollte. Haben die anderen PCs das? – mjolinor
