Once a day wordpress deletes all trashed items which had been in the trash for more then N days, where N stands for the value of EMPTY_TRASH_DAYS constant which may be defined in wp-config.php file.
This plugin presents a different way to control the number of trashed days. Instead of manually editing wp-config.php which is usually not convenient and somewhat dangerous, you can set the number of days in a settings page. 
In addition there is a tool to empty the cache from Items older the a specified number of days.
Usage: 
Get to the settings page via the menu “Options” >> “Empty trash” 
Get to the delete trash tool page via the menu “Tools” >> “Empty trash”
Network considerations: 
The plugin was not tested in a network installation, but it should work gibing the individual site admin a control over his trash which is possibly different then other sites on the network. 
The plugin do not have network wide settings
Important: 
For better or worse the plugin employs exactly the same deleting algorithm used by the wordpress version running the site.
Limitations: 
The plugin will not be able to function well if you have EMPTY_TRASH_DAYS set in your wp-confing.php

Trash emptier

Provides a configurable control over the trash emptying algorithm wordpress uses without changing wp-config.php

This plugin records which user actually trashed a post, which in a multi-author environment may not always be the original post author. This helps to maintain accountability for who was ultimately responsible for deleting a post. It also records when the post got trashed.
The admin listing of trashed posts is amended with new “Trashed By” and “Trashed On” columns that shows the name of the person who trashed the post or page and the date the post was trashed, respectively.
The plugin makes no assumption about who trashed a post, or when, for posts that were trashed prior to the use of this plugin (since the plugin could not have directly recorded information about the post’s trashing). The “Trashed By” and “Trashed On” values for those posts will remain empty. Put another way, only posts or pages trashed while this plugin is active will have the user who trashed the post/page and that date recorded.
