Disable Site Delete plugin only allows network administrators to delete a blog/site on a WordPress Multisite network. It does not allow blog owners to delete their blogs.
It works by doing that in 3 steps:-
<ul>
<li>Removes the delete Site link from tools menu for non network admins</li>
<li>Breaks out of wpmu_delete_blog function to avoid deletion of blog</li>
<li>hacks around option to avoid sending the delete confirmation mail to blog owner</li>
</ul>

By default, when you delete a post or page, any associated media files or attachments to that post do not get deleted. Keeping these orphan files to your server will eat up a lot of precious web space for no reason.
Using this plugin when you delete a post, any associated attachments will also get deleted automatically.
Before deleting any media file or attachment the plugin smartly checks that the attachment is not in use elsewhere, i.e. on any other post, page, or product.
