Bluetooth

[map71070]

My friend can send ringtones, wallpapers etc to my phone via Bluetooth but when I tried to send her some of mine it says Receiver cannot use this file or protected file. Is this because of the particular thing I downloaded? if so, what sort of file should I download so I can Bluetooth it to her?
Many thanks in advance
