ITUNES folder and My Music Folder

Question

My ITUNES folder doesn't appear to have as much music in it as My Music folder does.
Can I delete the ITUNES folder contents and reload My Music folder into it (Via ITUNES using Add A Folder - The folder being My Music)? 
Are the files linked between the ITUNES folder and My Music or does it duplicate the music MP3 files inside the ITUNES folder?  Thank you.

This doesn't quite address the question you've asked, but take a look at https://discussions.apple.com/message/17267509#17267509 for background.
I'd suggest if you're going to use iTunes you put all the media inside the iTunes Media folder rather than having some at the My Music. Without knowing more details I can't tell if the reason that My Music is that much bigger than iTunes is because everything has been duplicated, or because you also have lots of files in WMA format. I also can't say if deleting the current contents of iTunes and then reimporting wouldn't throw away stuff that only exists in iTunes at present.
It is much better to throw away stuff you've checked you don't need than to throw away too much and then discover you've made a mistake.
