when upgrading to mountain lion will it delete all my files?
Will an upgrade to mountain lion delete all my files so as to lose data or will my existing files be saved?
MacBook Pro, Mac OS X (10.7.4)
Your data will remain. Back it up anyway.

Everything should remain as it is. I would recommend doing a backup, though.
As others have already said you should be backing up your data before installing a major OS release. But why would you think your data would be deleted?
That's the difference between doing an upgrade or a fresh install. Mac OS 10.6 or .7 can be upgraded or even reinstalled over the top of the existing OS without affecting the user folder which contains all your documents, pictures, music, etc.
In order to do a fresh install you would have to used Disk Utility to wipe the drive before you do the installation.
