# readFileWrapper()

Reads data representing a file’s contents from the receiver and returns it as a file wrapper.

func readFileWrapper() -> FileWrapper?
```

## Return Value

Return Value A file wrapper containing the pasteboard data, or nil if the receiver contained no data of type NSFileContentsPboardType.

## Discussion

Discussion In macOS 10.5 and earlier, the file contents pboard type allowed you to synthesize a pboard type for a file’s contents based on the file’s extension. In macOS 10.5 and later, using the UTI of a file to represent its contents now replaces this functionality.
