# createFile(atPath:contents:attributes:)

Creates a file with the specified content and attributes at the given location.

```
func createFile(atPath path: String, contents data: Data?, attributes attr: [FileAttributeKey : Any]? = nil) -> Bool
```

## Parameters

`path`

The path for the new file.

`data`

A data object containing the contents of the new file.

`attr`

A dictionary containing the attributes to associate with the new file. You can use these attributes to set the owner and group numbers, file permissions, and modification date. For a list of keys, see [`FileAttributeKey`](/documentation/Foundation/FileAttributeKey). If you specify `nil` for `attributes`, the file is created with a set of default attributes.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the operation was successful or if the item already exists, otherwise <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion

If you specify `nil` for the `attributes` parameter, this method uses a default set of values for the owner, group, and permissions of any newly created directories in the path. Similarly, if you omit a specific attribute, the default value is used. The default values for newly created files are as follows:

- Permissions are set according to the umask of the current process. For more information, see umask.
- The owner ID is set to the effective user ID of the process.
- The group ID is set to that of the parent directory.

If a file already exists at `path`, this method overwrites the contents of that file if the current process has the appropriate privileges to do so.
