Joomla 2.5 has reached its end of life as for 12/31/2014. Please be advised this may be a security risk to your website. You can view more information about the end of life here.
Joomla 2.5 articles are assigned one of the following status:
An archived article in Joomla 2.5 is any article that you no longer want to be prominent on your Website. It is not exactly a trashed article, and it is not the same as an Unpublished article.
If you think about the literal term of archived, you can think of an archived article as one that has been filed away because it doesn’t have a high importance any longer. You’re not yet ready to throw the article away, but at the same time it is not an article that you want to flaunt on your website.
When you set an article as archived, it will no longer be shown in the article listing page within your Joomla 2.5 dashboard. If the article was set as a featured article, it will no longer show on featured article menu items. For users to find archived articles on your Joomla 2.5 website, you’ll want to create an archived articles module.
