When making backups of files while working on things we normally rename them with a _ on the end. i.e. renaming minecraft.conf to minecraft.conf_. GD still reads these preset conf files even though the extension has been changed to conf_.

Obviously not a major issue, but it could cause confusion for people trying to debug presets and such.
