# IsValid

> Returns true if the ContentFile handle is valid.

## Definition

* **Type:** Property
* **Namespace:** [Unity.Loading](/engine/6000.6/script-reference/unity/loading.md)
* **Assembly:** UnityEngine.ContentLoadModule

```csharp
public bool IsValid { get; }
```

### Remarks

This will be true immediately after the handle is returned from [ContentLoadInterface.LoadContentFileAsync](/engine/6000.6/script-reference/unity/loading/contentloadinterface/loadcontentfileasync.md). It becomes false after [ContentFile.UnloadAsync](/engine/6000.6/script-reference/unity/loading/contentfile/unloadasync.md) is called.
