object.DeleteFile file [, force]: This method is used to delete a specified file or files (using wildcards). The optional force parameter returns a Boolean value - True allows files with read-only attributes to be deleted, while False (default) does not. Trying to delete a read-only file without setting force to True will return an error. Note that an error also occurs if you try to delete a file that doesn't exist.
