How to extract ringtone from wp7 rom package?

Do you know how to customize the SMS prompt tone in WP7? It's not a text message. It's not an incoming call. I think the process is similar, but the other way around.

That's what you said. The ringtone that comes with the rom must be in the windows folder. Please install the file manager and enter the windows folder first. I know there are ten SMS reminders called1.wma2.wma. . . . . 10.wma If you mean the ringing of incoming calls or alarm clocks, it should be a wma file with another name. Copy and paste them into the nearest folder with the file manager (that's the name if I remember correctly), and then connect to the computer. On the computer, I can use the software that can convert my mobile phone into USB flash drive mode, and I can see the letters of my mobile phone in my computer. If you look for it in the folder, it should be there. It was my idea. I don't know if it's ok. . . Because I also follow this reverse step when customizing the SMS prompt tone, I think it should be feasible if I extract it externally. . . Give me the best. .
