Este tíquete no Fórum de suporte da Nokia sugere que você altere o atributo de arquivos / pastas que você não quer que o Nokia Music Player encontre como arquivos de sistema, talvez você possa tentar essa abordagem. Trecho:
To prevent a file or folder with ringtones from being listed in the MP3 player: 1. Get yourself a file manager that allows you to change file/folder attributes. Y-Browser will do the job
- Create a separate folder and place in it all the ringtones and melodies you want to hide from the player. I recommend using the memory card - this will help you repair the file system in case something goes wrong.
- Open the file manager from Step 1 (not the build-in File Manager) and navigate to the folder from Step 2.
- Change the attributes of the folder to 'System'. For Y-Browser highlight the folder and choose Options -> Attributes then set 'System' to 'Yes' and press Save.
- Exit the file manager and refresh the library of the Music Player. Now the folder/files are not shown in the Music Player/File Manager but are still listed on music file selection dialogs (like 'Ringing tone' option in Contacts).
