@mksBelper is coming from EagleFile.app with 10.000 webarchives (Thread: Updating webarchives).
He first wanted to update them, i.e. reload the content and save it if it’s fine. But now he’s considering whether using a mixed format strategy would be better. In 99% of cases he wants the current content of a URL so this script can be used to convert his webarchives with labels etc.
