NOTE: THIS GUIDE IS FOR WINDOWS. - But with slight variations applies to linux and mac machines as well.

# Overview

This is a simple guide for people who would like to move Unreal Engine 4 to a different directory (After installing it before). For example, if you were to install Unreal Engine 4 on C:/ and then later down the line you purchased another Hard Disk Drive and plug it into your PC. Now, you're running out of space on C:/ and want to move it to another directory.

# Steps to move Unreal Engine to a Different HDD

BEFORE WE START. MAKE SURE THE LAUNCHER AND UNREAL ENGINE 4 EDITOR ARE NOT RUNNING.

Sidenote: The directory where the unreal engine is installed may be different depending on your launcher/engine version. It may be under C:\Program Files\Epic Games\VersionNumber or under C:\Program Files\Unreal\VersionNumber.

  1. Create the folder where you want to move Unreal Engine to. In this case "D:\Unreal" is used

  2. Cut all the directories under the folder where Unreal Engine is installed and paste them to your desired location.

3)Make a link for each directory you moved: For example, if your install location is "C:\Program Files\Epic Games\" and you want to link a directory named 4.8 to "D:\Unreal\4.8", you would open a command prompt (Windows Key + R, then type "cmd" , then press Enter Key) and type:

cd "C:\Program Files\Epic Games\"

mklink /j 4.8 D:\Unreal\4.8

You also need to make a link for the other Engine versions as well as the Launcher and DirectXRedist folder.

You have now successfully moved whole Unreal Engine to a different folder.

P.S. The same concept applies to linux and mac machines. The link command is just different.
