All guest records are periodically deleted by a schedule tasks but in any case if a store admins wants to delete these guest account manually, then this features comes into play. This options enables you to delete the customers accounts created for guest visitors.

Deleting abandoned shopping carts: In nopCommerce application, when a guest visitor adds an item in the shopping cart but never checks out, the shopping cart is left under the guest account and considered as a abandoned shopping cart. For the maintenance purposes this must be deleted. This option enables you to delete all abandoned shopping carts created before the specified date.
Deleting old exported files: In nopCommerce application, when a file is exported, a copy also get saved on the server/database. This option enables you to delete all the exported files that were generated (like PDF, Excel etc) from the database.
