MeowApps - Media File Renamer Pro v3.7.3 - For cleaner & SEO friendly filenames

It automatically renames your media filenames depending on their titles. When files are renamed, the references to it are also updated (posts, pages, custom types and their metadata). A new column in the Media Manager will display to you the new ideal filename and a button will allow you to rename it straight away. You can lock and unlock the renaming automatic process through little icons.
