I follow the tutorials inside https://docs.unrealengine.com.
On the section of Landscape Quick Start Guide–>4. Creating Landscape Materials,Here is the writing“You can find
the textures located in the following folder located in the Landscapes Content example project.
/Game/ExampleContent/Landscapes/Textures/”
But，where is the " Landscape Content Example project"？

My English is poor, I'm sorry

It’s part of the Content Examples project, which you can download through the Epic Games Launcher under Unreal Engine’s Learn tab, under the Engine Feature Samples section.
