Windows: Libraries are a great feature of Windows 7 and up that allow you to pool several folders in one place. Librarian improves on the concept by allowing you to manage those collections more easily.
Librarian allows you to add or remove folders, change the default save location, and select the type of collection all in one place. It doesn’t do much that you can’t do from elsewhere, but many of these options are scattered throughout the OS. This app consolidates all of those options in one, simple window.
