Best way to transfer mp3's to Nokia C3? | Phone/Device Issues and Features | Consumer forum

When i connect via usb it gives me three options, ovi, media transfer and mass storage (or words to that effect).

I have used media transfer and deleted file & folders from the music folder and then copied different files & folders onto the phone. I have two problems.

1) some of the old folders are still on the phone even though the music folder appears empty in explorer on the computer.
2) some folders only have a few tracks or are greyed out etc.

What is the best way to copy my mp3's onto a C3?

Thanks
