Texture packs should be in .zip file format when downloaded. Windows users should move this file to the subdirectory %appdata%/.minecraft/resourcepacks. Mac OS X users find the correct subdirectory at /Library/Application Support/minecraft/resourcepacks. For Linux users, the correct directory to which to move the file is /.minecraft/resourcepacks/.
Once the file has been moved, start the game. Select "options" in the menu, then "resource packs." The new texture should appear in the list of resources. Click on it, then click "activate" to make it available in the game.Learn more about Accessories
