Exporting saves the current world as files used by the server and the game. In one go you can create a resource pack, a server registry, a .npbuild, a .schem and a Minecraft world folder. Importing reads a .schem schematic or a range of a Minecraft world into the editor and pastes it.
| What | Where |
|---|
| Export window | Build › Export: Resource pack piece · .npbuild (Ctrl+Shift+E) |
| Save directly as a Minecraft world | Build › Save as Minecraft world… |
| Resource pack only | Build › Build resource pack (Resource pack and HUD) |
| markers.json | Build › Export: markers.json (server markers) |
| Import .schem | File › Import: .schem (Sponge schematic), or Import .schem in the export window |
| Import a world | Import world in the export window |
- Open the export window with Ctrl+Shift+E.
- Under Target, check what to create (resource pack · server registry · .npbuild · .schem · world save (.mca)).
- Choose the Target version (default 1.21.11).
- Choose the Region (Whole world · split regions / Whole world · single file / Selection only).
- Click Export.
- Open the output folder with the Open folder icon. The Log shows the created files and warnings.
- Click Build › Save as Minecraft world… and choose a folder.
- Copy the created
<name>_world folder into %APPDATA%\.minecraft\saves\.
- Open it from the Minecraft single-player list. It is a Creative world with time fixed at noon and no mobs.
| Target | What it creates | Where it is used |
|---|
| Resource pack | Complete resource pack (standalone) or fragment zip | Server resource pack |
| Server registry | <name>_registry_vN.json | Server plugin (custom blocks · props · items) |
| .npbuild | Install file for the server build module — block entities · props · groups, markers.json with Include markers, scene.json with Include scene | Server plugin |
| .schem | Sponge v3 schematic | WorldEdit · FAWE |
| World save (.mca) | level.dat + region/*.mca + entities/*.mca | Single player · server world |
- scene.json holds scene actors, animations and world logic rules. It is not exported as a separate file; it goes inside the .npbuild (scene.json format).
- If there are sound emitters or block sounds,
<name>_sounds_server_vN.json is also created when you export the server registry.

item_display props placed by the editor or the server are turned back into editor props.- Other entities (mobs, item frames, etc.) are not imported.

More about versions is in Minecraft versions.
- Exports never overwrite. If the same name exists,
_v2 · _v3 … is appended.
- A complete resource pack gets a version number, as in
<name>_rp_vN.zip.
- The world folder is
<name>_world.
| Key | Action |
|---|
| Ctrl+Shift+E | Export window |
| Esc | Close the export window |
- If there are errors, no files are created. Fix the
[오류] lines in the Log first.
- For accurate prop sizes, check the resource pack too. Otherwise props are written at size 1 with a warning.
- If you export container items across format eras (before/after 1.20.5), names and enchantments are dropped and only type and count remain.
- Upload the resource pack and server registry according to the server’s
plugins folder settings. The resource pack SHA-1 lines are in .sha1.txt.
