How to Download Mods in "The Sims"by Warren DaviesUpdated September 22, 2017
A "The Sims" mod, short for modification, is a file that you can add to your "The Sims" installation to alter some aspect of the game. Mods typically alter gameplay and behavior as opposed to adding new objects to the game. Mods vary in the degree to which they change the game -- some make a behavior available to a character who ordinarily can't perform it, while others make larger behavior changes to multiple characters. To mod your "The Sims" game, find a site with the package files for the mod you want to use, and then install it into your game.
Create a folder on your hard drive in which to store your downloaded mods. Create a new folder for each mod that you download.
Locate a mod to add to your game. Either do a search for “Sims mods” or go to one of the many mod sites directly (links in Resources). Some sites require registration to access the downloads.
Download the mod by right-clicking it, choosing “Save Link As,” and then saving the file to your "The Sims" downloads folder.
Go to your "The Sims" download folder, right-click the file you just downloaded, and then click “Extract here.” If this option is not available, click “Open,” copy all the files, click the back arrow, and then paste the files into the same folder as the downloaded file.
Check the file type. If it has the Sims3Pack file extension, double-click it to load the Launcher, which installs the mod to your game. If you see two folders and a file, copy them to C:\Users\
