How to delete orders from magento?

[Dhiren]

Are you know how to delete all orders that you have made in Magento (http://store.modulesoft.in/manage-orders-by-orderbook.html)?:teleport:

This is quite strangely a function which is not currently available in the Mage back-end. The only way that can do this, is to remove all affected references from the database its self.

Your only options are to use a third party plugin, or to follow the manual steps, which can be found as a thread on the magento official blog.
