Install .package for TS3

Da SimsCri Simpedia.
Cubetti ico.gif Instruction to install custom contents in TS3

If you download custom content in .package format for The Sims 3, the installation method is quite different from The Sims 2.

WARNING we are talking about .package files but this doesn't mean you can put old The Sims 2 files into The Sims 3. The file format is the same, but files are totally different and incompatible. Don't try to use your old custom content in The Sims 3.

Alarm ico.gif WARNING!!
The following article refers to the Resource.cfg file needed after patch 1.12/2.7/3.2 that enables the game to load custom contents in .package format directly from the your My Documents/Electronic Arts/The Sims 3 folder. The old method to insert custom content in .package format is at the bottom of the page, click the spoiler to read it.

First installation

  • DO NOT insert .package files into your Downloads folder (My Documents/Electronic Arts/The Sims 3/Downloads) → if you put the files here the game will not read and load them.
  • After the patch 1.12/2.7/3.2 you can create a Mods folder to load custom contents in .package format directly in your My Documents/Electronic Arts/The Sims 3 folder.

Create the Mods folder

  1. Go to your The Sims 3 folder in My Documents (My Documents/Electronic Arts/The Sims 3).
  2. Right click, New→Folder
  3. Rename it to Mods
  4. Open your new Mods folder

Note for MAC

If you are using a MAC you have to follow the same steps. The folders you should create are the same too.


The first time you install custom content, you need an extra file: Resource.cfg. It is a file that modifies the game's settings without overwriting anything and it tells the game to load a new folder. In that folder you should keep all your downloaded .package files stored into subfolders.

You can find more information about this file and how to download it by reading HERE.

Have you inserted the Resource.cfg file??

Have you downloaded Resource.cfg eng and inserted it in My Documents/Electronic Arts/The Sims 3/Mods??
Are you sure it is in MY DOCUMENTS?
Are you sure that your game version is updated at least to 1.12/2.7/3.2?

Good, you can go ahead...

Subfolders creation

The new system to load .package files allows only subfolders. The game doesn't load files from the Mods folder, it reads only subfolders. The structure of the Resource.cfg_eng file allows you to create up to 5 levels of subfolders within the Mods folder. What does it mean? Let's consider an example:


Note: you can add some folders at each level, such as:


and so on.

If you add more subfolders the game doesn't load them. If you want to add more subfolders, you'll need to edit the Resource.cfg folder. Consider that 5 levels are a good compromise. More levels could overload your game and increase the loading time.

How to insert .package files

After creating the folders and some subfolders, your game is ready to read .package files, so, go back to your downloaded files.

Usually, everything you download is in .rar or .zip format. Extract them directly in My Documents/Electronic Arts/The Sims 3/Mods/SubfolderEX, or extract them to a temporary folder and then move them to My Documents/Electronic Arts/The Sims 3/Mods/SubfolderEX.

Open the game and you should see them.

File d3dx9_31.dll

Some custom contents, not all but in particular mods and hacks, require an additional file, called d3dx9_31.dll.
