In the case of email, all files are sent as attachments. You can also specify additional files by browsing for them when using the Email Form input screen (through both the user interface and the Print Wizard engine), or by specifying it on the command line for the Print Wizard engine:
printwiz.exe /email=abc@def.com /ac:\temp\file.doc myfiletoemail
Different behaviors may be noticed with different email options. Contact us for more information.
