Custom Content, usually called CC, is one of the best ways to customize your experience in The Sims 4. From realistic hairstyles and clothes to furniture, makeup, and gameplay tweaks, CC allows you to tailor the game exactly to your taste.
If you’re new to CC or feel confused about where files go, this guide will walk you through how to install CC in The Sims 4 step by step, explain the different file types, and help you avoid common mistakes.
What Is Custom Content in The Sims 4?
Custom Content is player-made content created by the community. It can include:
- CAS items (hair, clothes, makeup, skin details)
- Build & Buy objects (furniture, décor, clutter)
- Gameplay mods (scripts that change how the game works)
- Overrides (replacements for EA items)
Most CC is free and shared by creators on sites like Tumblr, Patreon, or CC finds blogs.
Step 1: Locate Your Mods Folder
Before installing anything, you need to know where The Sims 4 stores mods and CC.
Default Mods Folder Location
Windows
Documents > Electronic Arts > The Sims 4 > Mods
Mac
Documents > Electronic Arts > The Sims 4 > Mods
If you don’t see a Mods folder, launch the game once and close it. The folder will generate automatically.
Step 2: Enable Mods and Script Mods in Game
CC will not appear unless mods are enabled.
- Open The Sims 4
- Go to Game Options
- Select Other
- Check:
- Enable Custom Content and Mods
- Enable Script Mods
- Click Apply Changes
- Restart the game
After restarting, you should see a popup listing detected mods and CC.
Step 3: Download Custom Content Safely
Most CC downloads come as .package, .ts4script, or .zip/.rar files.
Common File Types Explained
- .package
Standard CC like hair, clothes, furniture, skins - .ts4script
Script mods that affect gameplay
These must be no more than one folder deep inside Mods - .zip / .rar / .7z
Compressed files that need to be extracted first
⚠️ Never place zip or rar files directly into the Mods folder without extracting them.
Step 4: Extract Files (If Needed)
If your CC comes compressed:
- Windows: Right-click → Extract All
- Mac: Double-click the file
Inside, you’ll usually find .package files (and sometimes instructions).
Step 5: Place CC Into the Mods Folder
Move your files into:
Documents > Electronic Arts > The Sims 4 > Mods
Recommended Folder Organization
You can organize CC into folders for cleanliness:
Mods
├── CAS
│ ├── Hair
│ ├── Clothes
│ └── Makeup
├── BuildBuy
│ ├── Furniture
│ └── Decor
├── Gameplay Mods
✅ .package files can be placed several folders deep
❌ .ts4script files must be only one folder deep
Step 6: Launch the Game and Check Your CC
When you open the game:
- A popup will show installed CC and mods
- Enter Create-a-Sim to check CAS CC
- Enter Build Mode to check furniture and décor
If items appear with a wrench icon, they are CC.
Common Problems and How to Fix Them
CC Not Showing Up
Check the following:
- Mods are enabled in Game Options
- Files are not still zipped
- Files are in the correct Mods folder
- CC is compatible with your game version
Game Crashes or Won’t Load
- Remove recently added CC
- Check for outdated script mods
- Clear cache files:
localthumbcache.package
- Update mods after patches
Missing Mesh Warning
Some CC requires a mesh (a base file).
Always read the creator’s download page carefully.
Tips for Managing Custom Content
- Don’t download too much at once
- Test CC in small batches
- Keep a backup of your Mods folder
- Remove broken or unused CC regularly
- Use tools like Sims 4 Tray Importer to identify CC
Is Custom Content Safe?
Yes, as long as you download from trusted creators and avoid shady sites. CC does not damage your computer, but outdated mods can cause bugs in-game.
EA allows CC and mods, but they are not officially supported.

Installing CC in The Sims 4 is simple once you understand the folder structure and file types. With the right organization and a little care, custom content can completely transform your gameplay and creativity.
