hier mal ein kleines Uploadtool kann vllt. anderen helfen ein paar sachen zu verstehen 
Es kann eine Datei oder mehrere auf einmal hochladen. Atm lädt es die Dateien immer in das selbe Verzeichnis, aber das kann man ja mit ner variable und nem Inputfeld hinzufügen. Achja falls iihr den Code anschaut denkt immer an mein Motto: Confused coding
Die benötigte ftp.au3 könnt ihr hier laden: Download
