Unreal Starting a New Project: The Content Browser

The Content Browser is at the bottom of the Unreal Engine UI. It houses all of your assets and created objects for your project. The side directory of the Content Browser has the different types of assets in the appropriate folders, such as Architecture, Audio, and Materials. There is a search bar at the top of the editor where you can search for your desired asset that you know is somewhere in the content folders.

You can also add a new asset straight from the Content Browser by right-clicking on a folder and choosing "New Asset." You can also rename and color asset folders to sort them easier. If you go to the View Options tab at the bottom of the Content Browser, you can unlock more assets by checking the Show Content options.
