The Enterprise Global file is not used for creating new projects. If you
wish to create new projects from a template, your organization should create
and save enterprise templates for those project types. Users can access
those enterprise project templates by clicking File - New, clicking the On
My Computer link in the sidepane, and then click the Enterprise Project tab
in the dialog.
The Enteprise Global file is meant to be used as your organization's
"library" of custom enterprise objects such as Views, Tables, Filters,
Groups, Fields, etc. It is also used to set the default currency for all
enterprise projects. Hope this helps.
