Merge Minecraft Nether and End Folders into One World Folder

Why Spigot and Paper Store Dimensions Separately

Spigot and Paper are popular Minecraft server options because they improve performance and allow plugins. One detail that surprises many server owners, however, is how these server types organize world files.

A standard Minecraft server stores the Overworld, Nether, and End inside the same main world folder. Spigot and Paper often split them into separate folders beside the main world folder instead. If your world is named `world`, the related folders may look like this:

• `world`
• `world_nether`
• `world_the_end`

That layout works fine while the server continues using Spigot or Paper. The problem appears when you switch to vanilla Minecraft, upload the world somewhere that expects the default layout, or open the world in singleplayer. In those cases, the Nether and End can look like they vanished. They have not been deleted. Minecraft is simply looking in a different place, which is rude but fixable.

To make the world compatible with vanilla Minecraft and singleplayer, move the dimension folders back into the main world folder:

• Nether data belongs in `DIM-1`.
• End data belongs in `DIM1`.

Before Moving Files

Stop the server before changing world files. Moving folders while the server is running can cause save errors, missing chunks, or partial transfers.

It is also smart to make a backup first. Dimension folders can be large, and a backup gives you a clean restore point if a folder is moved to the wrong location.

Confirm the Active World Name

1. Open your server control panel.
2. Find the current world name in your panel settings.
3. Write down the exact name, including capitalization.
4. Stop the server.
5. Open your FTP client or preferred file manager.
6. Log in and go to the server's main directory.

The default world name is usually `world`, but custom servers often use names like `Survival`, `SMP`, or `Season3`. The exact folder name matters.

Check for Existing Dimension Folders

Open the main world folder first. Look for either of these folders:

• `DIM-1`
• `DIM1`

If either already exists, rename it before moving anything else into the world folder. This prevents overwriting or mixing old dimension data with the files you are trying to restore.

For example, rename them to:

• `DIM-1-unused`
• `DIM1-unused`

Only do this if you are sure those existing folders are not the Nether or End data you want to keep. When in doubt, download a backup before renaming anything.

Move the Nether into the World Folder

The Nether for Spigot and Paper worlds is usually stored in a separate folder ending in `_nether`.

1. Return to the main server directory in your file manager.
2. Open the folder named `[world_name]_nether`.
3. Select the `DIM-1` folder inside it.
4. Choose Move.
5. Set the target directory to `/[world_name]`.
6. Leave the target name as `DIM-1`.
7. Submit the move.

For example, if the main world folder is named `Survival`, move `DIM-1` from `Survival_nether` into `/Survival`.

After the move, the path should look like this:

`/[world_name]/DIM-1`

Move the End into the World Folder

The End is handled the same way, except its folder name is different.

1. Return to the main server directory.
2. Open the folder named `[world_name]_the_end`.
3. Select the `DIM1` folder inside it.
4. Choose Move.
5. Set the target directory to `/[world_name]`.
6. Leave the target name as `DIM1`.
7. Submit the move.

For a world named `Survival`, the final path should be:

`/Survival/DIM1`

Once both folders are inside the main world folder, vanilla Minecraft and singleplayer should be able to load the Nether and End connected to that world.

Folder Layout After the Merge

After merging, the main world folder should contain the dimension folders directly inside it:

• `[world_name]/region`
• `[world_name]/DIM-1`
• `[world_name]/DIM1`

The `region` folder stores Overworld region files. `DIM-1` stores Nether region files. `DIM1` stores End region files. Minecraft naming is not glamorous, but it is consistent enough once you know the pattern.

Splitting the Dimensions Again

If you later move a vanilla world back to Spigot or Paper, you may need to split the dimensions back into separate folders. Some server versions handle this automatically, but not all do.

Split the Nether

1. Open your file manager and go to the main server directory.
2. Create a folder named `[world_name]_nether`.
3. Open the main world folder.
4. Select `DIM-1`.
5. Choose Move.
6. Set the target directory to `[world_name]_nether`.
7. Submit the move.

Split the End

1. Go to the main server directory.
2. Create a folder named `[world_name]_the_end`.
3. Open the main world folder.
4. Select `DIM1`.
5. Choose Move.
6. Set the target directory to `[world_name]_the_end`.
7. Submit the move.

After that, the folders will match the separate Spigot or Paper layout again.

Troubleshooting

The Nether or End Folder Does Not Contain DIM Files

Older Spigot or Paper builds may store the dimension data differently. Instead of placing `DIM-1` inside `[world_name]_nether`, the entire `_nether` folder may effectively be the Nether dimension. The same can happen with `_the_end`.

If there is no `DIM-1` inside the Nether folder, rename the relevant Nether folder to `DIM-1` and place it inside the main world folder. If there is no `DIM1` inside the End folder, rename the relevant End folder to `DIM1` and place it inside the main world folder.

The Nether or End Looks Reset

If the dimensions still appear fresh after the move, check these points:

• The server was stopped before moving files.
• `DIM-1` is directly inside the main world folder.
• `DIM1` is directly inside the main world folder.
• Old `DIM-1` or `DIM1` folders were renamed before the move.
• The active world name in the control panel matches the folder you edited.

Most reset-looking worlds come from placing the folders one level too deep, moving them into the wrong world folder, or leaving conflicting old dimension folders in place.
