Ordner Datum ändern
07.03.2014 15:05:11
Pepi
Ich habe einen Code gefunden, der das Erstelldatum einer Datei ändert. Das ist wunderbar. Leider funktioniert dieser Code nicht für Ordner (vieleicht braucht es eine Anpassung - ich verstehe den Code zuwenig!) Ich habe viele Ordner auf dem PC, die am TV in wilder Reihenfolge erscheinen, so will ich das Erstelldatum (Aenderungsdatum) ändern und jeweils um 1 Min. erhöhen, damit die Reihenfolge dem Orndernamen entspricht. (leider keine Sortiermöglichkeit beim TV)
hoffe auch einen Vorschlag
Pepi
