Choosing Which Packs to Play

The Sims 3 Expansion and Stuff Pack Manager lets you choose which Expansion and Stuff Packs to play with.

Before making your selection, install all of the Expansion and Stuff Packs you own. Only packs that you have installed will display in the Pack Selector. Once all of your packs are installed, locate the ones you want to play with, then check the checkbox next to the pack. Once you finish making your selections, press the Play button to launch The Sims 3 with the desired Expansion and Stuff Packs selected.

When choosing which packs to play with, we recommend selecting only a couple at a time. This will ensure you have the best game experience.

To help manage the packs, you can click the column headers to sort by:

Status – Sorts by enabled and disabled.

Title – Sorts alphabetically by title.

Installing and Uninstalling Packs

Visit Origin to install, uninstall, or purchase additional packs. All The Sims 3 Expansion and Stuff Packs can be found under The Sims 3 tile by selecting the Game Details option.

Backing Up Save Game Files

Making changes to the packs you play with may also affect your game save file. Specifically, if in The Sims 3 Expansion and Stuff Pack Manager you deselect packs that you have been playing with and load a game save that uses those packs, the game will replace the unloaded content with default items or remove them altogether. If you wish to keep a backup copy of the game save file for future use, locate the file in your computer’s directory and save a copy to your desktop.

Windows XP, 7, 8, and 10 – C:\Users\Username\Documents\Electronic Arts\The Sims 3\Saves
