The location you're looking in and seeing
Pristine Packages may potentially be the install folder for Sublime 2, but that's not where packages are actually stored (as you've noticed).
The actual location differs depending on the operating system that you're using and the method of installation (i.e. if you are using a
Portable installation), but the best way to determine the proper package location is to select
Preferences > Browse Packages from the menu, which will open a file explorer on the location that Sublime uses to store your packages.
