Under the ISO9660 standard,
there are some restrictions to remember.
The maximum nested folder depth is 8 (including the
root directory). File/folder names are limited to 31

Valid characters for folder/file names are letters A-Z (all
caps), numbers 0-9, and ‘_’ (underscore).

This device also can play back discs in Joliet, and other
standards that conform to ISO9660. However,
sometimes the file names, folder names, etc. are not
displayed correctly.

Enhanced CD (CD-Extra) and Multi-Session.

with Track At Once or packet writing.

Order of tracks

The unit plays the files in the order that the writing

MP3 Operation

Terminology

Bit rate

This is the “sound” compression rate specified for
encoding. The higher the bit rate, the higher the sound
quality, but also the larger the files.

Sampling rate

This value shows how many times per second the data
is sampled (recorded). For example, music CDs use a
sampling rate of 44.1 kHz, so the sound level is
sampled (recorded) 44,100 times per second. The
higher the sampling rate, the higher the sound quality,
but also the larger the volume of data.

Encoding

Converting music CDs, WAVE (AIFF) files, and other
sound files into the specified audio compression
format.

ID3 tag

Song information such as track titles, artist names,
album names, etc., written into MP3 files.
