.minecraft

.minecraft (or simply minecraft in OS X) is the folder Minecraft creates to run from. This folder includes the .jar files, sound, music, resource packs, personal options, worlds, etc.

Locating .minecraft

Locating the .minecraft folder is vital to install several mods as the mod files need to be placed in various folders in .minecraft.

OS	Path
Windows	%appdata%\.minecraft
Linux	~/.minecraft
Mac OS X	~/Library/Application Support/minecraft

If you're a Windows user and are unfamiliar with how to find your appdata folder, follow these steps:

1. Click Start → Run. If you don't see "Run" try holding down your "Windows" key and press the R key.
2. Type %appdata% (case doesn't matter but be sure to include the % markers) and click OK.
3. Open the .minecraft folder.

If you're a Linux or Mac user, the ~ in the path refers to your home directory. Folders startings with a . (dot) are hidden by default.

You can force the use of a resource pack by naming its zip file to resources.zip and placing it in the root folder of the world save. This feature is single-player only, there is an other way for servers to ask clients if they want to use the server resource pack.
