A String which specifies the full path (including the file name and extension) to where the MHT file will be created.
This method overwrites any files present at the specified path that have the same name without warning. Note that the .mht (or an appropriate) extension has to be specified in the path. After an MHT document has been created, it can be displayed in a Web browser.
