3-2. Using the audio system Items related to standards and limitations are as follows. • Maximum directory hierarchy: 8 levels • Maximum length of folder names/file names: 32 characters • Maximum number of folders: 192 (including the root) • Maximum number of files per disc: 255 l File names The only files that can be recognized as MP3/WMA and played are those with the extension .mp3 or .wma. l Multi-sessions As the audio system is compatible with multi-sessions, it is possible to play discs that contain MP3 and WMA files. However, only the first session can be played. l ID3 and WMA tags ID3 tags can be added to MP3 files, making it possible to record the track title and artist name, etc. The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags. (The number of characters is based on ID3 Ver. 1.0 and 1.1.) WMA tags can be added to WMA files, making it possible to record the track title and artist name in the same way as with ID3 tags. l MP3 and WMA playback When a disc containing MP3 or WMA files is inserted, all files on the disc are first checked. Once the file check is finished, the first MP3 or WMA file is played. To make the file check finish more quickly, we recommend that you do not save any files other than MP3 or WMA files or create any unnecessary folders. If the discs contain a mixture of music data and MP3 or WMA format data, only music data can be played. l Extensions If the file extensions .mp3 and .wma are used for files other than MP3 and WMA files, they will be mistakenly recognized and played as MP3 and WMA files. This may result in large amounts of interference and damage to the speakers. 264
