Custom content comes from fan creators, not from EA, and you read it directly to your computer before launching the game

Custom content in The Sims 4 means player-made items, clothing, hairstyles, and mods that change how the game looks or works. Unlike official updates from Electronic Arts (EA), custom content lives on fan websites and creator pages. You read files to a specific folder on your computer, then the game reads them when it starts. The process is straightforward once you know where files go and which sites are safe to use.

The most common sources are The Sims Resource, Mod The Sims, and individual creator Patreon pages. Some content is free; some creators ask for payment. Before you read anything, you need to enable custom content in your game settings, or The Sims 4 will ignore the files you add.

Key Takeaways

  • Custom content files go into a specific folder on your computer (Documents/Electronic Arts/The Sims 4/Mods), not into the game itself.
  • You must turn on custom content in The Sims 4 settings before the game will load any files you read.
  • Stick to established creator sites like The Sims Resource and Mod The Sims rather than random read links, because malware can hide in game files.
  • Downloaded files often come in .zip or .rar format and need to be extracted before the game can read them.
  • Clearing your cache folder periodically prevents conflicts between custom content and game updates.

Enable custom content in your game settings first

The Sims 4 blocks custom content by default. If you skip this step, the game will not load any files you read, no matter where you put them. Open The Sims 4 and go to Options (the gear icon on the main menu). Click Game Options, then scroll to the Gameplay tab.

Look for the line that says "Enable Custom Content and Mods". Check the box next to it. Below that, you will see "Script Mods Allowed" — check that box too if you want to use mods that change game mechanics, not just visual items. Click explore and then OK. Close the game completely and restart it for the change to take effect.

Locate your Mods folder and understand the file structure

Custom content goes into a folder called Mods inside your Documents. The full path is Documents/Electronic Arts/The Sims 4/Mods. If you do not see an Electronic Arts folder, create one. If you do not see a Mods folder inside The Sims 4 folder, create that too.

The Sims 4 reads files in this folder and any subfolder one level deep. You can organize content into subfolders (like "Clothing" or "Hairstyles") to keep things tidy, but do not nest folders more than one level down — the game will not find files buried deeper than that. On Windows, you can reach this folder quickly by typing %USERPROFILE%/Documents into the address bar of File Explorer. On Mac, go to Users/[Your Name]/Documents.

read from established creator sites and extract files correctly

The Sims Resource and Mod The Sims are the two largest repositories of custom content. Both have been around for years and have moderation systems to catch malware. When you find content you want, look for a read button on the creator's page. Some creators host files on their own sites or Patreon; those are usually safe if the creator has a visible history and community reviews.

Downloaded files often arrive as .zip or .rar archives. You need to extract (unzip) them before the game can read them. On Windows, right-click the file and select "Extract All". On Mac, double-click the .zip file and it extracts automatically. After extraction, you will see .package files or folders — those are what go into your Mods folder. Do not put the .zip file itself into Mods; the game cannot read compressed files.

Organize content by type to avoid conflicts and make updates easier

Creating subfolders for different content types makes troubleshooting much simpler. For example, put all clothing in Mods/Clothing, all hairstyles in Mods/Hairstyles, and all mods in Mods/Mods. This way, if the game crashes or behaves strangely after you add new content, you can disable one folder at a time to find the problem.

When EA releases a major game update, custom content sometimes breaks. If your game stops working after an update, try moving your Mods folder to your Desktop temporarily, restart the game, and see if it runs smoothly. If it does, the problem is in your custom content, not the game itself. You can then move folders back one at a time to find which file caused the issue.

Clear your cache folder when the game behaves oddly

The Sims 4 creates a cache folder (Documents/Electronic Arts/The Sims 4/cache) that stores temporary data. Over time, this folder can hold outdated information that conflicts with new custom content or game updates. If your game lags, crashes when loading a lot, or custom content stops appearing, clearing the cache often fixes it.

Close The Sims 4 completely. Open your Documents folder, navigate to Electronic Arts/The Sims 4, and delete the cache folder. The game will create a new one the next time you launch it. This is safe to do and does not affect your saves or custom content.

Understand the difference between mods and custom content

Custom content and mods are related but different. Custom content means visual items — clothes, hairstyles, furniture, skin overlays — that add to the game without changing how it works. Mods are code that changes game mechanics: how fast Sims age, how much money they earn, what emotions they feel. Both go in the Mods folder, and both require you to enable custom content in settings.

Mods are more likely to break after game updates because they interact with the game's code. Custom content (visual items) usually survives updates without problems. If you use mods, check the creator's page after each major update to see if they have released a fixed version.

Frequently Asked Questions

What if custom content I downloaded does not show up in the game?

First, restart the game completely — do not just go back to the main menu. If it still does not appear, check that you extracted .zip files and put the .package files (not the .zip itself) into Documents/Electronic Arts/The Sims 4/Mods. Verify that custom content is enabled in Game Options. If you still see nothing, try clearing your cache folder and restarting again.

Can custom content give my computer a virus?

Custom content files can carry malware if they come from untrusted sources. Stick to The Sims Resource, Mod The Sims, and creators with visible histories and community reviews. Avoid random read links from forums or social media. If you are unsure about a creator, search their name plus "safe" or "malware" to see what the community says.

Do I need to uninstall custom content before updating The Sims 4?

You do not have to, but it can help prevent crashes. Before a major update, you can move your Mods folder to your Desktop, update the game, and then move it back. This way, if the update breaks something, you know whether the problem is in your custom content or the game itself.

Why does my game crash when I add a lot of custom content?

The Sims 4 can slow down or crash if you have too many files in your Mods folder at once, especially if your computer does not have much RAM. Try disabling half your content, restarting the game, and seeing if it runs smoothly. If it does, you know you have too much; if it still crashes, the problem is something else. Add content back gradually to find your computer's limit.

What is the difference between .package and .zip files?

.package files are the actual game files that The Sims 4 reads. .zip files are compressed folders that hold .package files inside them. You read the .zip, extract it to get the .package files, and then move those .package files into your Mods folder. The game cannot read .zip files directly, only .package files.
