Tutorials/Map downloads

Maps generated in other players' games can be downloaded by the player and opened in his or her copy of the game.

Saved worlds are stored in different locations depending on the operating system. It is currently not possible to select where the .minecraft data folder, and thus the saved worlds folder, is stored.

Prior to Beta 1.3, there were five world slots, and custom names were not possible. To use more than five worlds then, it was required to rename and move folders. This is no longer necessary; there can be theoretically any number of worlds, each with their own names.

Prerequisites

 * An archiver utility, such as WinRAR or 7-zip
 * Patience the first time

Obtain the files
There are thousands of Minecraft saves to download off the Internet. Two of the best places to download them are www.planetminecraft.com and www.minecraftforum.net, but, of course, other sites may be used as well. Make sure the file you download is either a ZIP or RAR file. Other files may work as well, but it's not guaranteed.
 * Download your save
 * Save your new ZIP or RAR file in an easy-to-find location, such as your desktop.

Unzip your save

 * Double-click your save on your desktop. If it opens like any other folder, skip the next steps.
 * If Windows prompts you to choose how to open this file (even if it's not a ZIP or RAR), choose your archiver utility.
 * If you see a folder named data and a file named session.lock, then your good to go! Extract the folders to your desktop.
 * If not, the files are probably there, you just have to dig deeper. Some might have two folders named Mac OS X and your_save. Check every folder until you see data and session.lock. Once you find them, extract the folders to your desktop.

Put the files into Minecraft
Now that we have the files, we're going to put them in Minecraft's core folder.
 * Copy the folder off your desktop (Copy the folder one directory above data and session.lock. For example, if my data folder and session.lock file are located in your_save next to Mac OS X under your_save_multi.RAR, I would copy the your_save folder.
 * Open the Run dialogue box by pressing +  and typing %appdata%\roaming\.minecraft\saves and hit . You're at your Minecraft saves folder, and you'll notice all your worlds are here, too.
 * Paste the folder ( + ) into the saves folder
 * Open the new folder and check to make sure it has these folders in it, all right under "your_save."
 * data
 * DIM-1
 * DIM1
 * players
 * region
 * level.dat
 * levl.dat_mcr
 * level.dat_old
 * session.lock
 * Once they're all there, close .minecraft and launch the actual game

Find the save in Minecraft
Here's the hardest part: finding your new save in all your other saves. Once you find it, load it up and have fun!
 * Once Minecraft launches, click "Singleplayer"
 * The name of the folder you copied will be the greyed out name under the world name. Most likely, the save will be called "world"
 * The new save is usually all the way at the bottom, but that's not always the case. You might need to do some hunting.
