The functionality in this plugin was incorporated into the built in export feature in WordPress 3.0
Working with a single large export file can be difficult. Use this plugin to create multiple export files that contain sections of your blog. This plugin has been tested on WP & WPMU versions 2.7 – 2.8.4. The plugin may work on earlier versions of WP/WPMU.
All restriction options provided in the plugin are optional. If no restrictions are selected, this plugin generates the same export file as the export feature built into WP & WPMU.
Features
Export by any optional combination of:
<ul>
<li>Date Range – Start & end month/year</li>
<li>Author – Same as WP/WPMU built-in export</li>
<li>Category – Export a specific category</li>
<li>Content type – Choose either posts or pages</li>
<li>Post status – Choose Draft, Published, Scheduled or Private</li>
<li>Blog Tag/Category Terms – Choose whether to include the blog’s complete list of Tags and/or Categories</li>
</ul>
Support can be obtained through:
