You were playing minecraft, something unexpected happened which forced the client to close, and when you tried to start playing again, minecraft no longer recognized your world. This can also happen to the level if an SMP server stops unexpectedly.

How Often This Happens: 1/5

Fixable: 5/5

How to fix:
#Close MineCraft
#Open your saves folder. On windows, this folder is called:

%appdata%\.minecraft\saves

On Mac, The Folder is Called.

~/Application Support/minecraft/saves

#Find and open the file of the save that minecraft doesn't recognize.
#Find the file called 'level.dat' and rename it to 'corrupt.dat' (The file extension may not be shown, the file may appear as just 'level', in which case, rename it to 'corrupt')
#Find the file called 'level.dat_old' and rename it to 'level.dat'
#Reopen minecraft and try again. You have lost some items that were in your inventory.

You need to find your save files so you can do back them up, share them, fix them etc..., or you need to find minecraft's program files and install a mod, back them up, delete them, etc...


Usefulness: 5/5 (extremely useful)

Do ability: 5/5 (extremely easy)

Procedure:
#Close MineCraft (you shouldn't do anything with any of these files, including your saves, while minecraft is running)
#If you do not use windows, skip this step.
The minecraft data folder can be found at the following location. Copy and paste it into the address bar of any folder window to go directly to the minecraft data folder.

%appdata%\.minecraft

The variable %appdata% denotes a special system folder where a user's applications can store data. Save data is stored in the folder called 'saves', and the minecraft program files are stored in the folder called 'bin'.
#If you do not use mac, skip this step.
The minecraft save data is stored in a folder in your application support folder. Navigate to the following folder to access them.

~/Library/Application Support/minecraft

The ~ in the folder name is a special folder built into the system denoting your home directory, and is usually equivalent to '/users/'. Save data is stored in a folder called 'saves', and minecraft's program data is stored in a folder called 'bin'.
#If you do not use linux, skip this step.
***Linux instructions go here***
#If you do not host an SMP server, skip this step.
most SMP servers use their own internal libraries to run minecraft, and do not rely on external program files like those in minecraft's 'bin' folder. The saved level for an SMP server is usually within the folder from which the server is running, and is specified through the server configuration.
#if you do not use any sort of special launching conditions for your installation, skip this step.
Minecraft can be tricked into saving data almost anywhere by changing the values of the special variables it uses to find the save and data folders. If you use any special settings when launching, keep those in mind when searching for the minecraft's folder.

Rarity: 3/5

How to fix:

#Start Minecraft.

#From Minecraft's interface, select the pack.

This is a very useful think to know how to do if you are setting up a server, and may help troubleshoot issues you may encounter trying to configure your system to run it.
