# UnloadUnusedAssetsImmediate

> Unloads assets that are not used.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor](/engine/6000.5/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

## UnloadUnusedAssetsImmediate()

Unloads assets that are not used.

```csharp
public static void UnloadUnusedAssetsImmediate()
```

### Remarks

An asset is deemed to be unused if it isn't reached after walking the whole game object hierarchy, including script components. Static variables are also examined.

Set the `includeMonoReferencesAsRoots` parameter to false to ignore asset references from script properties and static variables. The unloaded assets load again on first use. This parameter is true by default.

This method differs from [Resources.UnloadUnusedAssets](/engine/6000.5/script-reference/unityengine/resources/unloadunusedassets.md) in that it will wait for asset garbage collection to finish before returning.
