Siternet

Siternet Post Deleter is a safe and controlled tool for bulk deleting WordPress posts in batches.
Instead of deleting all posts at once, the plugin allows administrators to remove posts step-by-step using a configurable batch size. This reduces the risk of server overload and accidental data loss.
Key features:
<ul>
<li>Batch-based deletion (adjustable size)</li>
<li>Optional category filtering</li>
<li>Permanent deletion (no trash)</li>
<li>Safe media cleanup</li>
<li>Featured image protection logic</li>
<li>Admin-only access with capability checks</li>
<li>Nonce-protected destructive actions</li>
</ul>
When deleting posts, the plugin also removes associated media. However, it includes a safety mechanism that prevents deletion of images still used as featured images in other posts.
This makes it suitable for content cleanup, migrations, and maintenance tasks.

This plugin delete all posts ( of any post type) from listing page in a single click.
Sometime it is too annoying and time consuming to remove all records from wordpress listing page. 
First of all selecting all data, with pagination and then sending to trash and then clear data. And if those data are totally unwanted then we might wish for a clear button and boom!!! all deleted. 
This plugin does exactly same.
Go to any admin listing page, with any post type. Find a delete all button. 
If all the data you want to clear for that certain post type just click the button.
Note: the data and it’s related meta will be cleared. So before cleaning make sure that none of the data are not useful at all.
