Excessive Disk space usage

Have about 650 products in my woocommerce store and diskspace was roughly 8GB
before installing WP-Lister Lite for Amazon after installing this plugin all the remaining 8GB that was available has been used up. Now I cannot even update plugins because of lack of Disk space. I have no choice but to delete the plugin, wasted my time assigning Amazon ASIN numbers to every product in my woocommerce store. The addition of large Amazon product listing template as well product image to each product is the cause for the rapid exhaustion of disk space. Addition of the template to each product should be an option as it will lead to exhaustion of disk space. Not practical for a store having one thousand plus products with a mix of variable products.
