The funny book like things are the world RAR files. You right click and unzip "here" or where ever you want them. They are the actual World files.
Put the un zipped sims 3 pack in your downloads folder. Use the game launcher to install the world. Put the saved world files in the Saves folder.
Start the game and they shpuld show up.
When I right click there are three options that have the book icon next to them: Extract File, Extract Here, Extract to SV(ALGPS) which one do I need to use?
EDIT: I clicked Extract Here and it didn't actually give me the opportunity to where to put them, I then moved them to my Sims Downloads file, loaded the launcher and they aren't on there to install, in my Downloads file there is a folder called SV(ALGPS) with five files in, is that right or do I need to change anything? The RAR file is also in my Downloads folder.
