From the developer: "Minis creates a personal mp3 database for you. If you have many mp3 files burn on CD or inside harddisk, Minis helps you get all information of the mp3 files and add them into a built-in database (with only 3 steps), so that you can search your file efficiently, even without the CD. Minis also supports other media files such as wmv/wma. In addition, Minis provides a 'Windows Explorer' like interface to enable you to search mp3 files in your local harddisk. Function to play the media file with Windows Media Player is also available and a search history will be kept for quick reference."
