# currentChunkStorageRange

The sample range in the storage container to load together with the current sample as a chunk.

```
var currentChunkStorageRange: AVSampleCursorStorageRange { get }
```

## Discussion

If the current chunk isn’t stored contiguously in its storage container, the property value’s [`offset`](/documentation/AVFoundation/AVSampleCursorStorageRange/offset) is `-1`. In such cases use [`AVSampleBufferGenerator`](/documentation/AVFoundation/AVSampleBufferGenerator) to obtain the sample data.
