Installation
You will need to navigate into the folders and unrar each .package and .Sims3Pack file.
All monthly items are in .package format. Depending on what version of the game you have installed, you can find the correct way to install these .packages at this tutorial page:Mod The Sims - Installing .package Files

The Cities and Buildings are in .Sims3Pack format.
The correct way when used with my The Sims 3 Ultimate Bundle (August 2011) [Full ISO/Simulation/2009-2011] upload is to just extract and drop the "Electronic Arts" folder to your "My documents" folder, unrar the .package and .Sims3Pack files and then run the game, go to "Downloads" and install them
