Media File Sizes is a WordPress plugin designed to enhance the Media Library experience by adding a column that displays the total space occupied by each media item. This includes not just the original images but also any additional sizes that may have been generated. This feature is especially beneficial for users managing websites with limited storage quotas, allowing them to monitor their media usage effectively.

Moreover, the ability to sort the Media Library by file size enables site owners to easily identify duplicate media items, streamlining the management process. This can help optimize storage and improve overall efficiency in managing multimedia content on WordPress sites.
