Every Unity project contains an Assets folder. The contents of this folder are presented in the Project View. This is where you store all the assets that make up your game, like scenes, scripts, 3D models, textures, audio files, and Prefabs. If you right-click on any asset in the Project View, you can choose Reveal in Finder (Reveal in Explorer on Windows) to actually see the asset itself in your file system.

Important Note: You should never move project assets around using the OS since this will break any metadata associated with the asset. Always use the Project View to organize your assets.
