Examples:
This response format is different from the legacy Soloist/edje/Duet format. There are
quotes around the file name. The full file name, including the path is displayed. The
legacy drive, disc,s pot number (DDSN) settings have been removed since they are no longer
used. The duration and elapsed time now use milliseconds instead of frames for the least
significant field. This change was also made for the DIRECTORY and LIST commands. Some
of the newer codecs and audio-only clips do not have 'frame' information, so the sub-second
data is now shown in milliseconds for all spots. This field is also shown as three digits
instead of two digits.
