Thread: Text Messages Contaning File

I want to find the file on my HTC-Device (HTC P3450) which is responsible for holding the text messages, Actually I want to save that file since in my memory the number of text messages have benn increased too much but all the messages are important to me, so I want to save them in a hard disk or other storage device.

So I need to know the file so I can modify it

Thanks in Advance
