        These extraFiles are needed so that psalm can find the OCA\ stuff when checking the epubviewer project

        For example here is an error if you remove those:

        ERROR: UndefinedClass - lib/Listener/FilesLoadAdditionalScriptsListener.php:26:27 - Class, interface or enum named OCA\Files\Event\LoadAdditionalScriptsEvent does not exist (see https://psalm.dev/019)
