# maximumFileTransferSize

The maximum size of a file that the RCS file transfer service can send.

```
var maximumFileTransferSize: Measurement<UnitInformationStorage>? { get }
```

## Discussion

This value is represented as a Foundation <doc://com.apple.documentation/documentation/Foundation/Measurement> that uses the <doc://com.apple.documentation/documentation/Foundation/UnitInformationStorage> unit type.
If the messaging service doesn’t limit the file size, the value is `nil`.
