# writeFileContents(_:)

Writes the contents of the specified file to the pasteboard.

```
func writeFileContents(_ filename: String) -> Bool
```

## Parameters

`filename`

The name of the file to write to the pasteboard.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the data was successfully written, otherwise <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion

Writes the contents of the file `filename` to the receiver and declares the data to be of type `NSFileContentsPboardType` and also of a type appropriate for the file’s extension (as returned by the `NSCreateFileContentsPboardType` function when passed the files extension), if it has one.

## See Also

[`-  readFileContentsType:toFile:`](/documentation/AppKit/NSPasteboard/readFileContentsType(_:toFile:))
