The world folder, typically named “world” sometimes along with “world_nether” and “world_end” are (obviously) the world stuff, and is all you need for importing a world. If you already have a working server and would like to use that world instead, you have 3 options:
-
Delete the existing world folder(s), and replace it with that one
-
Rename the existing world folder(s) to something else, and drag the new/old world folder in
-
Drag the existing world folder in, followed by changing the
level-name
in theserver.properties
file to match the world’s folder’s name.
Note: The world that you’d like to use has to have it’s folder named “world” unless changed in the server.properties
file; if changed there then the world must match whatever’s there.
You sure it’s just the world? Or is it an entire server?
Singleplayer worlds (as well as LAN and “standard” servers) both save and store player data inside the world folder. However though, when you have certain plugins such as Essentials
for example, the only plugin I know that changes the way that Minecraft saves player data, player data is then instead stored outside the world folder inside Essentials’ plugin folder under userdata
which can then be exported to standard Minecraft as in exported to the world folder for use without the Essentials plugin.
If it is an entire server and not just the world folder, then yeah you pretty much have everything conserved.
