Purge Orders

I know I can export orders, but is there a way to clean out the history once the orders are exported to save space? Would I have to just delete them or is there way?

Yes, you can only delete these orders. If you want to display more than 100 orders on the page, please add the &items_per_page parameter to the URL. E.g.:

http://demo.cs-cart.com/admin.php?dispatch=orders.manage&items_per_page=200

Note: you should export not only orders but also order items:
