How does this plugin backup Lightview files during a plugin update?
When the plugin is deactivated it attempts to make a backup copy of Lightview’s files in a directory named wp-content/plugins/.z-lightview-backup. This folder is prefixed with a period which will cause it to be hidden on most web sites so as not to appear out of place. You can prevent this folder and backup from being created by disabling it from the z-Lightview settings page.
