inbetweenbox automatically categorises files by their kind as soon as you import them, making it easy to find exactly what you are looking for without having to do anything. Group common files together using folders, or have inbetweenbox do all of the hard work for you with Smart Folders. Smart Folders automatically find and organize files in your library by their type or subject matter and automatically update when files are imported and exported from your inbetweenbox library. inbetweenbox can also watch folders on your Mac for new files (such as your downloads folder). When new files are added to a Watched Folder, they are imported automatically into your inbetweenbox library. It is even smart enough to leave your files alone until they have finished downloading.
