Clean Launcher User Guide

On first launch or reset, Clean Launcher will offer to create an /Auto Mods folder inside your /Mods directory.

Anything you drop into Auto Mods is handled automatically while Clean Launcher runs in the system tray. Archives are unzipped if needed, mods stay in Auto Mods, and non-mod files are sent where they belong — Tray files go to /Tray and Saves go to /Saves.

There’s no manual unzipping or copying required. For quick access, you can pin Auto Mods to Windows Quick Access and drop files in as you download them, ready to test or organize later.

Clean & Launch deletes temporary cache files and error logs, then launches The Sims 4 in one click.

You can optionally clear the cache only when your /Mods folder has changed, or open the EA App if you need to be in offline mode. You can set the app to remember your selections, too.

Scan Mods checks your /Mods folder for common issues that can stop mods from working correctly or cause unexpected problems in-game.

It looks for buried script files, zipped mods that haven’t been extracted, duplicate files, and incorrect game settings—then offers to fix what it finds. Nothing is changed without your confirmation, and you’ll always see exactly what’s being addressed.

Running a scan is a quick way to catch problems early and keep your /Mods folder clean, compatible, and ready to play. It currently tracks all my (midnitetech) mods, and lets you know if you have an outdated version, or are missing a dependency.

Organize Mods gives you a live, folder-tree view of your /Mods directory, so you can see exactly how everything is laid out in real time.

You can drag files or folders to reorganize them, create new folders on the fly, and use Ctrl+click or checkboxes to select and move multiple items at once. Changes are applied instantly, so what you see is what’s actually in your /Mods folder.

If you make a mistake, Undo Last Move lets you roll back your most recent action—no hunting things down or starting over.

Mod Profiles let you save different mod folder setups and switch between them safely and easily.

Your current /Mods folder is stored as your Default Mods—a protected backup of your usual setup. You can then create additional profiles for testing, updates, or lighter play styles and switch between them with a single click. Whatever is in your /Mods folder when you hit Create New will be your new Profile.

If changes are detected before you switch profiles, Clean Launcher will prompt you to save them, so nothing is lost.

Mod Profiles make it easy to play while waiting for updates, testing new mods, or just for seeing if you really can go without that folder of CC you've been hoarding since 2014.

If you need to replace the contents of a profile, you can do that from Mod Profiles → More, where you can also see your backups, restore your original, or change your backup location. All profiles and backups are stored outside your Sims 4 folders and can be restored at any time.

The Backup feature lets you create a safe, compressed copy of your Mods, Saves, Tray, or everything at once, stored in a location you choose.

Clean Launcher packages your files into a zip archive, making it easy to keep organized backups before updates, testing new mods, or making big changes. Your original folders are never altered during the process.

Large folders may take a while to compress.

Before uninstalling, make sure Clean Launcher is fully closed. If it’s running, right-click the Clean Launcher icon in the system tray (by the clock) and choose Exit. You can also disable Start with Windows from the tray menu or from Settings in the main menu.

Once closed, uninstall Clean Launcher as usual from Add or Remove Programs in Windows.

If you’ve enabled Clean Launcher to start with Windows, the auto-start entry can be removed either from the tray menu or via Settings before uninstalling.

Your Mods, Saves, Tray files, and backups are not deleted when you uninstall.

Does Clean Launcher modify my game files?

No. Clean Launcher works only with your Mods, Saves, and Tray folders. It does not modify game files or core installation data.

Is anything changed without my permission?

No. Actions like backups, profile switches, scans, and fixes always require confirmation. Clean Launcher won’t delete or move files silently.

Why does my antivirus flag Clean Launcher?

Clean Launcher is a small, unsigned Windows utility that interacts with your Mods, Saves, and Tray folders. Some antivirus programs flag tools like this due to heuristic scanning, not because the app is malicious.

Clean Launcher does not include malware, spyware, or data collection. If your antivirus blocks it, you may need to add an exception or allow it manually. You’re also welcome to scan the installer or executable with VirusTotal for additional reassurance.

Can Clean Launcher run in the background?

Yes. You can set Clean Launcher to start with Windows using the ⚙️Settings icon in the main menu. When enabled, it runs quietly in the system tray, and features like Auto Mods remain active.

What happens if I close Clean Launcher?

Clean Launcher will run in the tray unless you exit it or don't have autostart enabled. When it isn’t running, background features like Auto Mods won’t be active. You can relaunch it at any time—or enable Start with Windows (⚙️Settings) to keep it running automatically.

Where are my profiles and backups stored?

Profiles and backups are stored outside of your Sims 4 folders, in a separate location managed by Clean Launcher. This keeps them safe from game updates and repairs.

You can see their location by right-clicking Clean Launcher in the tray and choosing Open Installation Folder, or from the More menu in Mod Profile Manager.

Will uninstalling Clean Launcher delete my files?

No. Uninstalling Clean Launcher does not delete your Mods, Saves, Tray files, profiles, or backups. Everything remains exactly where it was. Disabling Auto Mods will prompt you if you want to delete the folder itself, and it's contents.

Is Clean Launcher Windows-only?

Yes. Clean Launcher is currently available for Windows only.

Scan Mods is telling me I have buried scripts when I don't?

Create a Full Report from the Settings menu, and check the path of your Mods folder. If it doesn't read '\The Sims 4\Mods', you need to set your Mods folder path (⚙️Settings).
