Synchronize Creative Zen with MediaMonkey

My Creative Zen player came with a software to synchronize it with my local music folders. But the software is not really synchronizing, it only copies files from the local folder to the player. If I delete a file locally, it stays on the player…
To solve this I’ve installed MediaMonkey. It’s free and  a nice little tool to manage your music.
Synchronizing is configured in Tools > Options > Portable/Audio Devices. The option to delete files from the player is located at the Auto-Sync tab.
