I didn't get any good feedback and I know there are probably people out there wanting to do this so here is how you do it. This works on the EVO Shift and on the Verizon Droid 2 Global, I have both phones and have done this on each of them.
I downloaded AndExplorer, I can't believe there isn't a file explorer on the Shift??? Anyway easy to download, doesn't do anything but explore the files on the phone and allow you to work with them, so I haven't had any problems with it, just a great app.
If you launch AndExplorer you can then browse the phone as well as the SD card just like Explorer on your computer.
Browse the phone deviece to the folder System - Media - Audio.
Once in the Audio folder you will see the folders for the sounds, they will read Alarms - Alert - Notifications and Ringtones. There may be a couple others but you don't have to use them.
Open the Alarms folder for example, hit menu - more - select all.
Once all the sound files are selected hit menu and the Copy/Paste button, it will bring up a window where you can select copy.
Once they are copied, navigate to the folder you want to put them in like Notifications, or if you setup the folder structure for sounds on your SD card like in my directions below you can go to your SD card.
Once your in the folder where you want the sounds, hit menu and then the Copy/Paste button, a window will pop up and you can select Paste, all your sounds from the other folder will go in.
Now you can also copy the files from every folder on your phone and then navigate to your SD card and past the files there. If you want all sound files to be available then just create this folder structure on your SD card:
Open your SD card, make a folder called Media
Open the Media folder and make a folder inside called Audio
Open the Audio folder and make 4 folders inside it, Alarms - Alert - Notifications - Ringtones
Now just paste all the sounds from all 3 folders on your phone in to each of these folders. You can also throw in any other sounds you may like. Just remember when you add a sound to one folder you might as well add it to all of them so the sound will be available in all the sound settings for Ringers, Alerts, Notifications or Ringtones.
Once your finished, turn off your phone, pull the battery, wait a few seconds and then put the battery back in and boot the phone up. All your sounds should now be available to you where you want them. No rooting involved.
