If your game is crashing, lagging, or behaving strangely, learning how to uninstall mods in The Sims 4 is one of the fastest ways to fix it. Mods and custom content can completely transform gameplay, but they can also break after updates, conflict with each other, or cause serious bugs if not managed properly.
In this guide, you’ll learn exactly how to remove mods, uninstall Reshade, and fix common issues so your game runs smoothly again.
Where Mods Are Stored in The Sims 4
Before you uninstall anything, you need to know where mods are located.
On PC, your mods folder is here:
Documents > Electronic Arts > The Sims 4 > Mods
Inside this folder, you’ll usually find:
- .package files (custom content like clothes, furniture)
- .ts4script files (gameplay mods)
If your game is having problems, this is the first place you need to check.
How to Uninstall Mods in The Sims 4 Properly
Simply deleting random files isn’t always enough. Here’s the correct way to uninstall mods safely:
- Open your Mods folder
- Select the mod files you want to remove
- Delete them completely (don’t leave partial files)
- Empty your recycle bin
- Launch the game
After removing mods, always test your game before reinstalling anything.
If you’re using cheats while testing, it’s worth knowing that you can also unlock extra tools using the hidden objects cheat in The Sims 4, which gives you access to additional items that can help troubleshoot builds and saves.
How to Remove All Mods at Once (Quick Fix Method)
If you’re not sure which mod is causing problems, do this:
- Move the entire Mods folder to your desktop
- Launch The Sims 4
- Start a test save
If the game works fine, the issue is definitely mod-related.
From here, you can:
- Add mods back in small batches
- Identify the broken file
- Remove only the problematic mod instead of everything
This is the fastest way to isolate issues.
How to Uninstall Reshade in The Sims 4
Reshade isn’t stored in your Mods folder, so removing it is slightly different.
To uninstall Reshade:
- Go to your game installation folder
(usually Program Files > Origin/Steam > The Sims 4) - Delete these files if present:
- dxgi.dll or d3d9.dll
- reshade-shaders folder
- ReShade.ini
- Launch the game again
If your game was crashing or showing visual glitches, removing Reshade often fixes it instantly.
Fixing Issues After Removing Mods
Sometimes problems continue even after uninstalling mods. Here’s how to fully clean your game:
Delete Cache Files
Go to your Sims 4 folder and delete:
- localthumbcache.package
This file stores old mod data and can cause bugs if not cleared.
Repair the Game
If issues persist:
- Open EA App or Origin
- Right-click The Sims 4
- Select Repair
This will restore any broken game files.
Check Script Mods Settings
In-game:
- Go to Game Options
- Other
- Disable Script Mods
Restart the game after changing this setting.
