# AsyncReadManager

> With the AsyncReadManager, you can perform asynchronous I/O operations through Unity's virtual file system. You can perform these operations on any thread or job.

## Definition

* **Type:** Class
* **Namespace:** [Unity.IO.LowLevel.Unsafe](/engine/6000.7/script-reference/unity/io/lowlevel/unsafe.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static class AsyncReadManager
```

## Remarks

**Note**: On Windows and XBOX platforms, `AsyncReadManager` uses DirectStorage API for optimized file I/O operations when enabled in the **Player settings** > **Other Settings** > **Configuration** > **Enable DirectStorage**. For more information, refer to the documentation on [Optimize performance using DirectStorage](/engine/6000.7/manual/platform-specific/windows/develop/directstorage.md).
