For Security and scalability reasons, as confirmed in this documentation <https://cloud.google.com/appengine/docs/standard/php/googlestorage/>, when you application is deployed to App Engine, it is deployed to a local file system that is not writable.
Hence, my recommendation would be that instead of attempting to delete the bad files, why do not remove the bad files from your local copy of your application code and then you can deploy a new version of the Application to App Engine. You can then direct traffic away from the older version <https://cloud.google.com/appengine/docs/standard/php/migrating-traffic> or perhaps delete <https://cloud.google.com/sdk/gcloud/reference/app/versions/delete> the Old App Engine application version <https://cloud.google.com/nodejs/getting-started/delete-tutorial-resources#deleting_app_versions> . -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
