# segmentFileOutputURL

## Declaration

```swift
var segmentFileOutputURL: URL { get }
```

## Discussion

Discussion The URL of the file where this incremental segment should be written to. AVAssetWritingPlanner will request each incremental segment to be written to a different file. If the file already exists from a previous session, the client should delete it to allow the subsequent asset writer session to succeed.
