Folder Album Artwork is a lightweight tool that you can use to automatically populate music album folder icons with artwork.
Folder Album Artwork isn't a tool to fetch album artwork from the web, however, it only detects existing artwork in folders, grabs the info and makes them the default folder icons.
Folder Album Artwork is very easy to navigate. Simply drag over one or more folders to populate subfolders automatically. With this tool you can process thousands of folders with a single motion.
The app also comes with a ‘Quick mode’ that lets you drag folders directly onto the app icon rather than having to open the app. It even remembers your previous sessions settings!
