A template file cannot be uploaded to ConfTool Pro directly.
Please
upload the template file to your main website and make it available via a download link on your "information for submitting authors" page or similar.
To include it in ConfTool Pro,
add the link to the template for each submission type / track separately.
Please go to:
Overview => Settings => Manage Submission Types / Conference Tracks…and edit the relevant submission types / tracks.
In the field "Submission Details" enter the download link using HTML.
Example:
Please consider our <a target="_blank" href="http:://www.example-conference.edu/template.dot">template</ a> for your submission.
For this purpose please also refer to:
HTML Basics.
Hint: You could also think about including the link for the template in the e-mail for the call of papers.
