# PreloadBehavior

> Options for preloading the table collections flagged in the Editor.

## Definition

* **Type:** Enum
* **Namespace:** [Unity.Localization](/engine/6000.7/script-reference/unity/localization.md)
* **Assembly:** UnityEngine.LocalizationRuntimeModule

```csharp
public enum PreloadBehavior
```

## Remarks

Preloading runs when localization initializes and again when the selected locale changes. Only the table collections flagged for preloading in the Editor take part; everything else loads on first use. Set the behavior through [LocalizationSettings.PreloadBehavior](/engine/6000.7/script-reference/unity/localization/localizationsettings/preloadbehavior.md).
