This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are two
levels of regulations.
Level 1: The file name is in 8.3 format (8
character file names, with a 3 character
file extension. File names must be com-
posed of one-byte capital letters and num-
bers. The “_” symbol may also be
included.)
Level 2: The file name can have up to 31
characters (including the separation mark
“.” and file extension). Each folder must
contain fewer than 8 hierarchies.
Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft
®
. It compresses files into a size
smaller than that of MP3 files. The decod-
ing formats for WMA files are Ver. 7, 8,
and 9.
