You can usually choose any name you like for the folders you create to organise your Unity project. However, there are a number of folder names that Unity interprets as an instruction that the folder’s contents should be treated in a special way. For example, you must place Editor scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary in a folder called Editor for them to work correctly.
This page contains the full list of special folder names used by Unity.
The AssetsAny media or data that can be used in your game or Project. An Asset may come from a file created outside of Unity, such as a 3D model, an audio file or an image. You can also create some asset types in Unity, such as an Animator Controller, an Audio Mixer or a Render Texture. More info
See in Glossary folder is the main folder that contains the Assets used by a Unity project. The contents of the Project window in the Editor correspond directly to the contents of the Assets folder. Most API functions assume that everything is located in the Assets folder, and so don’t require it to be mentioned explicitly. However, some functions do need to have the Assets folder included as part of a pathname (for example, certain functions in the AssetDatabase class).
Scripts placed in a folder called Editor are treated as Editor scripts rather than runtime scripts. These scripts add functionality to the Editor during development, and are not available in builds at runtime.
You can have multiple Editor folders placed anywhere inside the Assets folder. Place your Editor scripts inside an Editor folder or a subfolder within it.
The exact location of an Editor folder affects the time at which its scripts will be compiled relative to other scripts (see documentation on Special Folders and Script Compilation Order for a full description of this). Use the EditorGUIUtility.Load function in Editor scripts to load Assets from a Resources folder within an Editor folder. These Assets can only be loaded via Editor scripts, and are stripped from builds.
Note: Unity does not allow components derived from MonoBehaviour to be assigned to GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary if the scripts are in the Editor folder.
Editor scripts can make use of Asset files loaded on-demand using the EditorGUIUtility.Load function. This function looks for the Asset files in a folder called Editor Default Resources.
You can only have one Editor Default Resources folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Asset files in this Editor Default Resources folder or a subfolder within it. Always include the subfolder path in the path passed to the EditorGUIUtility.Load function if your Asset files are in subfolders.
Gizmos allow you to add graphics to the SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary View to help visualise design details that are otherwise invisible. The Gizmos.DrawIcon function places an icon in the Scene to act as a marker for a special object or position. You must place the image file used to draw this icon in a folder called GizmosA graphic overlay associated with a GameObject in a Scene, and displayed in the Scene View. Built-in scene tools such as the move tool are Gizmos, and you can create custom Gizmos using textures or scripting. Some Gizmos are only drawn when the GameObject is selected, while other Gizmos are drawn by the Editor regardless of which GameObjects are selected. More info
See in Glossary in order for it to be located by the DrawIcon function.
You can only have one Gizmos folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Asset files in this Gizmos folder or a subfolder within it. Always include the subfolder path in the path passed to the Gizmos.DrawIcon function if your Asset files are in subfolders.
You can load Assets on-demand from a script instead of creating instances of Assets in a Scene for use in gameplay. You do this by placing the Assets in a folder called Resources. Load these Assets by using the Resources.Load function.
You can have multiple Resources folders placed anywhere inside the Assets folder. Place the needed Asset files in a Resources folder or a subfolder within it. Always include the subfolder path in the path passed to the Resources.Load function if your Asset files are in subfolders.
Note that if the Resources folder is an Editor subfolder, the Assets in it are loadable from Editor scripts but are stripped from builds.
When you import a Standard Asset package (menu: Assets > Import Package) the Assets are placed in a folder called Standard AssetsA collection of useful assets supplied with Unity. Unity ships with multiple Standard Asset such as 2D, Cameras, Characters, CrossPlatformInput, Effects, Environment, ParticleSystems, Prototyping, Utility, and Vehicles. More info
See in Glossary. As well as containing the Assets, these folders also have an effect on script compilation order; see the page on Special Folders and Script Compilation Order for further details.
You can only have one Standard Assets folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Assets files in this Standard Assets folder or a subfolder within it.
You may want the Asset to be available as a separate file in its original format although it is more common to directly incorporate Assets into a build. For example, you need to access a video file from the filesystem rather than use it as a MovieTexture to play that video on iOSApple’s mobile operating system. More info
See in Glossary. Place a file in a folder called StreamingAssets, so it is copied unchanged to the target machine, where it is then available from a specific folder. See the page about Streaming Assets for further details.
You can only have one StreamingAssets folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Assets files in this StreamingAssets folder or a subfolder within it. Always include the subfolder path in the path used to reference the streaming asset if your Asset files are in subfolders.
During the import process, Unity completely ignores the following files and folders in the Assets folder (or a sub-folder within it):
This is used to prevent importing special and temporary files created by the operating system or other applications.
