WordPress has introduced a powerful feature of Trash in their new release of version 2.9. We recently checked out this feature and we were greatly impressed by this feature.
This feature is powerful in case of comment and post moderation, by managing some changes in the role management plug-in. This helps in revert the deleted posts and comments.
Trash for Comments
The comments that are deleted moved to trash and can be retrieved later on if found genuine. Check the screen shot to see the new look of this feature.
Now remove the comments permanently from the trash.
Trash for Posts
The posts that are deleted are moved to trash and can be retrieved back just by clicking on Undo. The deletion does not move the post permanently, and later on you can remove it permanently from their.
Remove the post and it moves to the trash.
Screen shot for permanent deletion of the post.
This permanent deletion of the post removes only the content of the post not the media associated with the post. If a post is removed the images and files associated are not removed the server. If you want to remove the media attached to the post, you have to delete those files from the Media list.
