/// Synchronously creates the file.

/// If recursive is false, the default, the file is created only if all

/// non-existing parent paths are created first.

/// If exclusive is true and to-be-created file already exists, a
/// PathExistsException is thrown.

/// If exclusive is false, existing files are left untouched by createSync.

/// Throws a FileSystemException if the operation fails.

/// @description Checks that if `exclusive` is `true` and to-be-created file
/// already exists, then a [PathExistsException] is thrown.
