.minecraft

.minecraft (or simply minecraft in OS X and Linux) is the folder Minecraft creates to run from. This folder includes the .jar files, sounds and music, your personal options, worlds, etc.

Locating the .minecraft folder is vital to install several mods as you need to place the mods files in various folders in there.

Location:
 * Windows: %appdata%\.minecraft
 * Mac OS X: ~/Library/Application Support/minecraft
 * Linux: ~/.minecraft
