If you’re also wanting to delete all of your Library lots/rooms/households then you can delete the “Tray” folder in the game documents folder, or you can individually delete them by opening the gallery (also the F4 key shortcut), navigating to My Library, then selecting each and clicking the trash can.

Remember that deleting the library won’t affect any lots/rooms/households that you’ve uploaded to the gallery. Those are saved to your account and can be downloaded to your game again easily.

The game -will- rebuild the Tray and the “saves” file when it is loaded up.

And if you just want it all deleted in one fell swoop, you can delete the whole The Sims 4 documents folder and repair your game. Or uninstall/reinstall. To repair the game, just right click on it in Origin and select “Repair Game”.

Make a New Game by clicking the + sign on the Welcome screen. (It’s to the right of the big Load Save button!) The world will be freshly new like the other Save Games don’t exist (except for any lots you’ve left in your Library will still be there!) And don’t forget to name your Save Game by selecting “Save As” when you save. =)

Me personally? I’ve done all of these methods. I don’t suggest messing with the folders if you’re inexperienced, and if you do, always backup! Uninstalling/Reinstalling is the easiest and least hands on, so I tend to do that if I need to. =)

Unless you prefer multiple save games for different legacies and such, it is completely unnecessary! In your game, you can select Manage Worlds where you can easily build, bulldoze, and place lots.

If you have a lot you want to save, all you have to do is either save it to your library or even better, upload it to your cloud. That way, if your game is reinstalled or your files corrupted, you will still have that lot saved on your Origin account in the gallery!

The Sims 4 boasts being easy to just grab and go. In a recent patch, Maxis has added their lots into our library so if you prefer to delete one from your game, you can easily get it again from there (a lot like the bin in The Sims 3 at the bottom of the screen).

Your library will be available to you no matter which Saved Game you are accessing, so if you build a house in one and save it to your Library or Gallery, you can load up a different save game and place it. I personally do this for my “Build” save file where I just play around in Build/Buy Mode.

Like you, in the previous games, I was afraid to use my Bulldoze tool because it felt… heartbreaking! But knowing that I can easily bring a lot back if I don’t like a different one there gives me a peace of mind. I hope this helps!
