Unreal Snippet: Reducing engine installation size

Unreal Engine takes a considerable amount of storage on your hard drive, even more so when you install multiple versions. Here is a quick tip on reducing the overall size of your Unreal Engine installs.

Unreal Snippet: Reducing engine installation size

Unreal Engine typically installs with additional resources and target platforms as a baseline. For example -- Android, iOS, and Linux are all additional target platforms included by default. If you're not planning on developing on one or all of these platforms, you can easily uninstall them.

Simply follow these steps to do just that --

  1. Open the Epic Game Launcher
  2. Navigate to the Unreal Engine Library
  3. Click on the dropdown arrow next to the launch button on one of the Engine installed engine versions.
  4. Click options
  5. Uncheck everything you don't need
  6. Click apply

For an Unreal Engine developer targeting only Windows, the engine size will be halved - going from 38~ GB down to 18~ GB.
