Sync destination mask is under File location in you onedrive image.

How do you sync file to device as if you use Send to -> Copy then it will copy filename from drive not as sync mask?

NOTE: I can't see your dropbox image as it is linked to personal folder not to image share link.

Hy,
Thx for yr remarks,

I don't understand yr password remark.

Pls see https://1drv.ms/u/s!AsFpIakqkHuAr3Yakc45aq_HeDIw ; where can i indicate to not include <track#> in the filename?

The image is behind a password.

If you're seeing the filename, you can tell sync to not include <Track#> in the Filename in the Device Profile (Tools > Options > Portable Device Sync).

Hey,
When I play on my car radio MM playlists I have synced to an USB stick I see a serial number (01 on the attachment), the artist and the title.https://www.dropbox.com/search/personal?query=1121&search_session_id=63331105171192889286050882344659&search_token=l8%2B86hsuTN23%2FhSBpKNANGT6PyISCix8ys%2BicijctBk%3D
How to re-organize to not show the serial number??
