WP Media Folders is a WordPress plugin with 2 main features:
Type a real media URL structure and the plugin will do the rest for you: create folder, sub folders, rename and move the media in the proper location. A new field is added on the media edition window that allows you to update the full path and name of all media. The old media URL will be also replaced automatically in the databases tables to avoid any broken links.
Import and synchronize media structure (folders and sub-folders) with the JoomUnited plugin, WP Media Folder.
WP Media Folder allows media management using virtual folders (custom taxonomy) in the WordPress Media Library. This plugin will create real server folders based on that.
