does upgrading to OS Mountain Lion delete all my files???

I heard that the new operating system is coming up for macbook pros and i'm really excited to buy it. My concern is that is it going to delete my old saved files and songs from my computer?

MacBook Pro, Mac OS X (10.7.4)

Upgrading an existing system does not erase your files. However, anything can happen, so it's wise to have a backup of your current system just in case.
