Abstract: A multiple-file facsimile feature for a fax printer driver allows combination of multiple files into a single facsimile transmission via the computer application programs in which the files were created, without the need to later identify and select the files a second time in order to create the multiple-file fax. The feature is advantageously implemented on a LAN-based computer, such as by a C-language program. When fax transmission of a file is requested, a dialog box containing dedicated buttons for the various functions involved in multiple-file fax creation is displayed by the fax printer driver, with a list containing the names of the files that have been added to the multiple-file fax displayed in a subwindow. The Add-to-List function converts each selected file to a faxable file that is saved in the temporary directory, adds the file name to the multiple-file fax list, and transfers the user back to the calling application program.
