Much of MB V3.2.6827 sync functionality works with the Creative ZEN portable device. Here's some info you may find useful.
1) To get MB to access a ZEN, you must first set Preferences, Devices,
[✓] detect MTP devices.
2) MB's default device config for a Creative ZEN (
Music,
Settings) is less than ideal e.g. excludes playlists.
I recommend:
a) In Device, Music, set
[✓] synchronise playlistsIf you don't want unplaylisted tracks too, set
[✓]synchronise music.
b) In Device, Settings:
* set
(*) preserve folders and filenames This is to avoid
this bug.
* set
playlists path: My Playlists\ * set
save as format:
PLA.
For safety, I also set:
[✓] delete tracks that are not on the auto-sync list from the device on the fly conversion
[_] split files with a cuesheet into individual tracks artwork storage
(*) do not copy artwork.That makes:


Note: If you need to restore your device config to the default, unplug the device,
in Preferences, delete it, and plug it in.
3) Issues
* Sync to MTP device that already contains some of the same track files fails and crashes the device. Workaround: first
delete all files from the device .
↗* Playlists synced by MB show as zero length, which doesn't stop them playing but causes interoperation fails with our programs.
↗* Preview's folder paths are often incorrect but the actual paths on the device are correct.
↗* On the device Music node, Folders fails to show correct path(s).
↗This issue found on a previous version might be present still:
* Playlist sync can fail with "Unable to find the specified file".
