# Set Up Package Folders

This is a Basic Procedure tutorial page. It explains how to perform a single procedure which is required in many different contexts.

The first step in making mods or creating any sort of script that will be compiled into a .U file (a package) is setting up package folders. This is just a small hierarchy of folders within your game's Base Directory. Source code (UC files) and resources such as textures and models go into these folders. The Unreal Engine compiler, Ucc, will then know to make them into the final package that the game can then execute.

## The main folder

This folder must be inside your game Base Directory, and the name of this must match the name of your eventual package. For example,

{Base Directory}\YourModPackage

When Ucc compiles, it will know that this folder must be used to make YourModPackage.U from what it finds inside the folder.

## Sub-folders

Within this folder, you need subfolders, one for each type of resource. If you don't have any of a particular resource, you don't need the folder.

{Base Directory}\YourModPackage\Classes
  This is the directory that should hold all of your UC files. This is mandated by the compiler itself. Your code will not be built if you use anything else.
{Base Directory}\YourModPackage\Textures
  This directory should be used to hold any HUD textures, object skins, and other graphics used by your mod.
{Base Directory}\YourModPackage\Models
  This is where you put the *.3d files for any meshes your classes import and use.
{Base Directory}\YourModPackage\Sounds
  This directory should be used to store any custom sounds used by your mod.

It is advisable to store a copy of your mod's INT file in the {Base Directory}\YourModPackage directory for safekeeping.
