Playlist creation for USB keys

Hi,
As a new user of MP3tag I'm having problems in creating .m3u playlists without including the absolute path of the tracks.
I.e., while I get files with content like this:

#EXTM3U
#EXTINF:274,Adriano Celentano - Ancora Vivo
E:\Adriano Celentano\C'e Sempre un Motivo\Adriano Celentano - Ancora Vivo.mp3
#EXTINF:256,Adriano Celentano - Mari Mari
E:\Adriano Celentano\C'e Sempre un Motivo\Adriano Celentano - Mari Mari.mp3
#EXTINF:327,Adriano Celentano - C'e Sempre un Motivo
E:\Adriano Celentano\C'e Sempre un Motivo\Adriano Celentano - C'e Sempre un Motivo.mp3

I would like to obtain a content like this one:

#EXTM3U
#EXTINF:274,Adriano Celentano - Ancora Vivo
Adriano Celentano - Ancora Vivo.mp3
#EXTINF:256,Adriano Celentano - Mari Mari
Adriano Celentano - Mari Mari.mp3
#EXTINF:327,Adriano Celentano - C'e Sempre un Motivo
Adriano Celentano - C'e Sempre un Motivo.mp3

Can aybody suggest a way to do it automatically ?

Thanks in advance.

Do you have the setting for relative paths enabled at "Options > Playlist" ?

Are the files and the playlist file on the same drive?
