If you use CurseForge to play Minecraft with modpacks and want to restore a backup of your world, this guide is for you. Whether something went wrong in-game or you just want to load an older version of your world, restoring a backup is simple once you know where to place the files.
This article will show you how to load your backup world using the same modpack — such as Fabulously Optimized — so you can keep using your favorite performance mods like Sodium, Iris, or Zoomify without losing your progress.

⚙️ Step-by-Step: Restoring Your Backup World in CurseForge
1. Open the Modpack Folder
Each modpack in CurseForge has its own separate folder, including its own saves
directory for worlds.
To find your modpack’s saves folder:
- Open the CurseForge app
- Click Minecraft, then click “My Modpacks”
- Find and click on your modpack — e.g., Fabulously Optimized
- Click the three dots (•••) next to the Play button
- Choose “Open Folder”
- Inside this folder, find and open the
saves
directory


This is where your modded worlds are stored.
2. Extract Your Backup World
If your backup is a .zip
file:
- Right-click the
.zip
file - Select “Extract Here” or “Extract to [folder name]”
- Make sure the extracted folder contains:
level.dat
region
folderplayerdata
folder- etc.
These files are necessary for Minecraft to recognize your world.
3. Move the Backup Folder to the Modpack’s Saves Folder
Now that your backup folder is extracted:
- Drag or copy that folder into the
saves
folder of your modpack
It should look something like this:
CurseForge > Minecraft > Instances > Fabulously Optimized > saves > YourBackupWorld
Make sure you’re not dragging the .zip
file, but the actual folder that contains level.dat
and other world files.
4. Launch the Modpack
- Go back to the CurseForge app
- Click Play on your modpack (e.g., Fabulously Optimized)
- Once Minecraft opens, go to Singleplayer
- You should now see your backup world listed
Just click it and start playing! Everything should load with the modpack’s performance enhancements active.
The reason this works is because performance modpacks like Fabulously Optimized don’t add new blocks or items to your world. Instead, they improve how Minecraft runs by adding visual or quality-of-life upgrades. That means your world will work perfectly, even when restored from a backup.
🧠 Pro Tips
- If your world doesn’t show up, double-check that:
- It’s inside the correct
saves
folder - The folder contains
level.dat
- You can rename the folder if you want the world to have a different name in the Minecraft menu
- If you’re worried about future issues, consider making regular backups of your world
