This file structure is how it should look like for XULRunner applications running on Linux and Windows. For developers who are developing on MAC OSX, please visit the following link Deploying XULRunner 1.8 to find the specific file structure to follow.

Notes:

In the file structure shown, some of the filenames and olders are italicized filename and folders. Users can rename these files or folders if they wish.
