Incredible 4G - Stock Ringtones, Notifications and Alerts file location?

[Nyobie]

I think the file location is hidden for the HTC Incredible 4G ringtones, notifications and alerts and if that's indeed the case, can anyone provide me with the path(s) for the files? I've successfully copied a folder full of each, onto my SD Card so I can now use some of my favorites which I've stored over the years but I'd like to eliminate duplicates but the stock sounds are hidden somewhere. They don't come up in a search of either the Phone Memory or my SD Card but I know they're somewhere. It's ok if I have to root my phone. I'm on a mission to find the rooted ROM for ICS which came with the phone I purchased a few days ago at the VZ store. Thanks!
