Basically, yes, it is all replicated, and this is how to stop that happening.
On my Mac, I go into Preferences, then the general tab. There is an option to select "Copy files to itunes music folder when adding to library." It's in a similar place on the PC version.
Do NOT check this.
If it is checked, uncheck it. This option will duplicate all your music in your itunes folder. You can keep this checked if you want all of your music in your itunes folder, otherwise make sure it is unchecked. When you have done that, you may delete all the music in your itunes folder. Except , of course, any cds that you imported into itunes and have no copy of elsewhere.

Does this make sense?
