Transferring content from samasung galaxy s2 to pc then from pc back phone gives me the message your files may not play on the device are you sure u want to transfer them etc.. and I'm wondering why its saying that?

I've connected my phone via usb cable and I'm not using kies. This is straight up windows explorer stuff.
