Where are files downloaded by Xcode being stored?

Hi, I just installed Xcode on my macbook pro (I use Xcode at work) and it is downloaded some other files (iOS 6 Library etc) at the moment. I really like apple packaging all of Xcode and its components into a single app file and distributing it because I can clearly see how much of space files related with development takes on my computer etc. But are those new files being downloaded also gonna go in the same place (inside Xcode.app) ? If not where are they gonna be stored?

Thanks in advance.

 

I think I found the answer to my own question. They are going to inside the Xcode.app it seems. I could see the path the files are being installed by going to Xcode preferences.
