I'm not sure i completely understand? All the files are on your drive.
The i386 folder is not on your drive as it contains compressed versions of the actual files. The files in this folder make up the Program Files initial state as well as documents and settings and windows folders.
if you want to see every file that is on your computer, you can always use search and type *, this will display all folders and files.... but the reason why you want to do this still escapes me. Is there something you are looking for?
