Then is possible to open multiple files without microsoft word or any other word processor software to manipulate.
In the sense "open" to operate the files, not to edit or write in the common sense of the word.

And the user will not see the opened files in the common use of the term open a file with "microsoft word".

Consequently we don't need to open the microsoft word files with microsoft word software.

Anyway my question is up !

Do you know software to manipulate rtf files without opening or see the file with microsoft word or any similar program ?
Do you know software to "programmatically open" word files ?
