I just switched to a new computer and I need to copy my sound files over from the previous. Scratch says that it stores it's sounds/costumes/sprites on the current computer (and the old one) in the C:\Program Files (x86)\Scratch\Media\Costumes folder but when I look there I see just the default sounds/costumes/sprites. On my old computer I had hundreds of sounds and not one shows up. Am I looking in the wrong place?
(Note: I have hidden files and folders set to show.)

Never mind, I dug around for a long time and found it was located in a REALLY out-of-the-way location. It's file path is (Windows 7):

C:\Users\ Your User's Name Here \AppData\Local\VirtualStore\Program Files (x86)\Scratch

If some miracle happens and a Scratch administrator/creator finds this post, can they please explain to me why the sounds people export are put here and not in the Program Files (x86) folder?

EDIT: Note that some of the sounds/costumes/projects folders may not be there - they are created when you add content to the default stuff.
