I don't need to test my programs. I have an error-correcting modem.

The Unreal Base Directory[edit]

This directory is where the game itself is installed. By default, it's called {drive}:\{game name}, eg C:\UnrealTournament, C:\WheelOfTime etc. Throughout the Unreal Wiki, you'll see it referred to as {Base Directory}. Within this directory there are several sub directories which varies depending on the engine version.

Script Directories[edit]

Precompiled Script[edit]

Unreal Engine 3[edit]

Precompiled scripts for this engine version will go in one of two directories:
{User Documents Directory}\My Games\{game name}\UTGame\Src
{Base Directory}\Development\Src

Unreal Engine 2[edit]

Same as for exported scripts, precompiled scripts go in package directories in the games {Base Directory}.

Exported Script[edit]

Unreal Engine 3[edit]

Exported scripts for this engine version will go in:
{User Documents Directory}\My Games\Unreal Tournament 3\UTGame\ExportedScript

Unreal Engine 2[edit]

Exported scripts for this engine version will go in the games {Base Directory}.

The User Directory[edit]

In unreal engine 3 things were changed some and it now uses the user documents directory for storing some things. As an example UT3 will use the directory:
{User Documents Directory}\My Documents\My Games\Unreal Tournament 3
