This is the World Downloader mod, originally by nairol. I took over development in March 2012, updating it, fixing bugs and adding some new features through version 1.7.2. I just have not had time to work on it since then. :(

Only because of the hard work from the Minecraft Forum community, this great tool continues! Please give your thanks to soccerguy3, UltiNaruto, julialy, Net32, El_garoo, Pokechu22, and of course Nairol for keeping it alive.

Important usage notes:

  • You need to open chests while downloading or their contents cannot be saved.
  • The mod can only save chunks which are sent by the server as you move around. If you see the chunk while downloading, then it is saved! If you do not move around, it will likely only save 10 chunks (160 blocks) in each direction.
  • The seed is not saved automatically. You must be op to request the seed with the /seed command. World Downloader will pull the seed automatically from the server response.
  • When you click “stop download”, wait until the world is saved to disconnect. You will be notified in chat.
  • Some entities such as Fireworks will freeze the client if used while downloading. Known bug.
