CD Library is an organizer for your CD collection. It will keep all your disks contents and will let you save comments for each file. It is very customizable - you can add categories for your CDs. The browser presents your CD contents like a tree letting you easily browse through the contents. Because it is free, as a database we used HypersonicSQL, an open source project. But, if you have another database already installed on your system and a jdbc driver for that database, you can configure it very easily. The application was tested against Oracle and MySQL.
