Installing content in The Sims 4

This page explains how to handle and install your custom content.  

Note that if your downloads are in zipped files, you will need to extract the files from the zips first before installing them.  

Installing lots, rooms and Sims

Lots, rooms and Sims are accompanied by a number of different files, all of which need to be placed in the TRAY folder:

Documents/Electronic Arts/The Sims 4/Tray

The files you place in the Tray folder include:


  • trayitem
  • blueprint
  • bpi (files

We also have a detailed guide on installing a lot into your game neighborhood!


  • trayitem
  • room
  • rmi files


  • householdbinary
  • trayitem
  • sgi
  • hhi files

If by chance you find any package files included with your lot, room or Sim, these need to be placed in the Documents/Electronic Arts/The Sims 4/Mods folder, not in the Tray folder.

Once you've installed your lots, rooms or Sims, they should show up in your personal gallery in the game. 

Installing everything else...

Custom content is created in package files (that is: files with a file extension of .package - for example: adultbluedress.package).  If your content is in a ZIP file, you'll need to extract the files from the zip first.

Package files are placed directly into your MODS folder:

Documents/Electronic Arts/The Sims 4/Mods

If you prefer, you can organise your downloads into folders in your Mods folder.  This is perfectly safe provided you have the file resource.cfg in your Mods folder which instructs The Sims on how many folders deep to look for your content.  If that file is missing, you can create it yourself easily with a simple text editor like Notepad.

The TSR Custom Content Manager

If all this sounds like too much hassle, we also offer a Custom Content Manager for our VIP members.  The CC Manager:

  • downloads AND installs all your content for you without you having to worry about what is placed where
  • provides images of the content you have installed, what it is, who made it - and gives you a link back to the page where you downloaded it
  • allows you to uninstall content easily, including anything installed in the TRAY folder
  • keeps you updated whenever any content you've downloaded has been updated by the creator and install the update on your behalf
  • allows you keep using it even without VIP (VIP is only required for downloading new content or keeping existing content up to date)

You can keep and continue to use the TSR CC Manager even without VIP.  VIP is only needed to install new content with it or keep existing files up to date.
