# dataless

File is a dataless placeholder (content is stored remotely).

## Declaration

```swift
static var dataless: FileFlags { get }
```

## Discussion

Discussion The system will attempt to materialize the file when accessed according to the dataless file materialization policy of the accessing thread or process. See getiopolicy_np(3). The corresponding C constant is SF_DATALESS. note: This flag is read-only. Attempting to change it will result in undefined behavior.
