When you need to upload a Minecraft world to your server, the World Manager in the LPV5 panel does it without FTP. It is a complete, dimension-aware world toolkit: you can list every world with its size and seed, download a world as a ZIP, upload a new one from a file or a URL, switch which world the server loads, and delete worlds safely with an automatic backup first. It understands both the Paper folder layout and the vanilla single-folder layout, so your Overworld, Nether and End all move together correctly. This guide covers each action in turn and flags the offline-only operations you need to plan around.
What the World Manager Does
The World Manager lists, downloads, uploads, switches and deletes worlds on your server, and it is dimension-aware across the Overworld, Nether and End. For each world it shows the size on disk and the key level.dat information, including the seed, the world's default gamemode and the Minecraft version that created it. That level.dat readout is genuinely useful: you can confirm a downloaded world's seed before you commit to it, or spot that a world was made on an older version than your server.
- Loafhosts runs Java Edition servers, so the World Manager works with standard Java world folders
- Reading the seed, gamemode and version from level.dat means you do not have to load a world just to inspect it
How It Handles World Layouts
Minecraft does not store dimensions the same way on every server, and the World Manager handles both common layouts for you. On Paper and similar servers, the three dimensions live in separate folders: world for the Overworld, world_nether for the Nether, and world_the_end for the End. On a vanilla single-folder layout, the dimensions are nested inside one world folder, with the Nether in the DIM-1 region directory and the End in the DIM1 region directory. The tool keeps these grouped so a download or upload always moves the whole world, not just one dimension.
- Paper layout uses world, world_nether and world_the_end as three sibling folders
- Vanilla single-folder layout keeps the Nether under DIM-1 and the End under DIM1 inside the main world folder
Download a World as a ZIP
The download action packs a world into a single ZIP and hands you a signed link to grab it. This is the right way to take a backup you can keep locally, move a world to another server, or hand a build to a friend. Because all the dimension folders are grouped, the ZIP contains the full world rather than just the Overworld.
- Sign in to LoafHub at hub.loafhosts.com
- Open your Minecraft server and open the World Manager
- Find the world you want in the list
- Choose Download to pack it into a ZIP
- Use the signed link to download the ZIP to your computer
- Download a world before any big change so you have a known-good copy you control
- The seed shown in the world list is a quick way to confirm you grabbed the right world before downloading
Upload a World from a File or URL
Uploading installs a world from a ZIP, and you can supply that ZIP in two ways: pick a file from your computer, or paste a direct URL and let the panel fetch it. The second option is handy for large maps already hosted somewhere, since the server pulls the file directly. Uploading is one of the operations that needs the server offline, because the world files cannot be safely written while the server has them open.
- Stop the server from the Console tab
- Open the World Manager and choose Upload
- Either select a world ZIP from your computer or paste a direct download URL
- Start the upload or fetch and wait for it to finish
- Switch to the new world if you want it loaded, then start the server
- Upload requires the server to be offline first
- Make sure your ZIP contains a real world folder structure, not just an extra folder wrapped around it

Switch the Active World
Switching changes which world the server loads by updating the level-name setting to point at the world you choose. This lets you keep several worlds installed, for example a survival map and a separate creative build, and flip between them. Like uploading, switching needs the server offline, because level-name is read at startup.
- Stop the server from the Console tab
- Open the World Manager
- Choose Switch on the world you want to load
- Confirm the switch, which updates level-name
- Start the server, which now loads the selected world
- Switching does not delete the previous world, it just stops loading it, so you can switch back later
- Because the active world is set by level-name, the World Manager and the Config Editor are looking at the same setting
Delete a World Safely
Deleting removes a world from the server, and the tool builds in two safeguards. First, it automatically creates a backup before it deletes, so a world is never truly gone the instant you remove it, though that automatic backup is retention-limited rather than permanent. Second, deletion requires you to type a confirmation, which stops a mis-click from wiping a world. There is one rule the tool enforces for you: you cannot delete the world that is currently active. Switch to a different world first, then delete the old one.
- Stop the server from the Console tab
- If the world you want to remove is active, switch to another world first
- Open the World Manager and choose Delete on the target world
- Type the required confirmation text
- Confirm to back up and then remove the world
- Delete requires the server to be offline and cannot target the currently active world
- The automatic pre-delete backup is retention-limited, so download a ZIP first if you want to keep the world permanently
Plan Around Offline Operations and Large Worlds
Three actions, switch, upload and delete, all need the server offline, while listing and downloading can be done at any time. It is worth grouping your offline work so you only take the server down once. Be patient with large worlds too: a multi-gigabyte world takes real time to pack into a ZIP, upload, or back up, so let those operations run to completion rather than cancelling them.
- Listing worlds and downloading them work while the server is online, so inspect first and only go offline when you are ready to change something
- For a big map, kick off the upload or download and let it finish in the background instead of refreshing the page
- Large worlds take time to pack, transfer and back up, which is normal and not a sign anything is stuck
