Database is a feature allowing the media box to play the same type of file among different storage medium. For example, the 'music' folder shows all the music files in the SD card, USB flash drive, and HDD. The classified files are shown in three specified folder, namely 'MUSIC', 'MOVIE', and 'PHOTO'. When a storage media is disconnected from the media box, the database will be updated. The files in the disconnected storage media would no longer be shown in the folder(s).
