\fB\-defaultextension\fR \fIextension\fR
Specifies a string that will be appended to the filename if the user
enters a filename without an extension. The default value is the empty
string, which means no extension will be appended to the filename in
any case. This option is ignored on Mac OS X, which

\fB\-confirmoverwrite\fR \fIboolean\fR
Configures how the Save dialog reacts when the selected file already

confirmation dialog be presented to the user.  A false value requests
that the overwrite take place without confirmation.  Default value is true.
