 success. It will fail if the file does not exist, 
 \helpref{Create}{wxtextfilecreate} should be used in this case.

 Change the file on disk. The {\it typeNew} parameter allows you to change the
 file format (default argument means "don't change type") and may be used to
 convert, for example, DOS files to Unix.
