Then open a ticket. I found similar one, but nobody checked there why folder is so big: [https://github.com/rullzer/previewgenerator/issues/129](https://github.com/rullzer/previewgenerator/issues/129)

P.S. It turns that changing of config.php will _not_ automatically recreate smaller/bigger previews. This is how to do it [https://github.com/rullzer/previewgenerator/issues/94#issuecomment-355745556](https://github.com/rullzer/previewgenerator/issues/94#issuecomment-355745556) run pregenerate command afterwards.
