Hummer 2007 H3 - Manual (Page 223)

The player will be able to read and play a
maximum of 50 folders, 50 playlists, 10 sessions,
and 255 files. Long file names, folder names,
or playlist names may use more disc memory
space than necessary. To conserve space on the
disc, minimize the length of the file, folder, or
playlist names. You can also play an MP3 CD that
was recorded using no file folders. The system
can support up to 11 folders in depth, though,
keep the depth of the folders to a minimum
in order to keep down the complexity and
confusion in trying to locate a particular folder
during playback. If a CD contains more than the
maximum of 50 folders, 50 playlists, 10 sessions,
and 255 files the player lets you access and
navigate up to the maximum, but all items over
the maximum are ignored.
Root Directory
The root directory is treated as a folder. If the
root directory has compressed audio files,
the directory is displayed as F1 ROOT. All files
contained directly under the root directory
are accessed prior to any root directory folders.
However, playlists (Px) are always accessed
before root folders or files.
Empty Directory or Folder
If a root directory or a folder exists somewhere
in the file structure that contains only folders/
subfolders and no compressed files directly
beneath them, the player advances to the next
folder in the file structure that contains compressed
audio files. The empty folder does not display.
No Folder
When the CD contains only compressed files, the
files are located under the root folder. The next
and previous folder functions does not function
on a CD that was recorded without folders
or playlists. When displaying the name of the
folder the radio displays ROOT.
When the CD contains only playlists and
compressed audio files, but no folders, all files
are located under the root folder. The folder down
and the folder up buttons search playlists (Px)
first and then go to the root folder. When the
radio displays the name of the folder the radio
displays ROOT.
