Never mind ... found it ... several options for @jiandu cc to consider/sort through ...
Course action fields
An absolute path to a backup file (.mbz) to import in the course.
(This means the full path to your course, for example /home/yourmoodle/public_html/moodle27/transfert/backup.mbz . If you are unsure of this, look at include_path in Site administration>Server>PHP info.)
This allows you to specify actions to be taken for every course uploaded.
If you are creating courses without a shortname, you can use this field to automatically generate a shortname. This field accepts two placeholders: %i for the ID number, %f for the summary.
A backup file (.mbz) to import in the course after create/update.
Restore from course
The shortname of a course to import content from after create/update.
Reset after upload
Whether to reset the course after creating/updating it.
Will have to test that some day and compare it to a moosh method. Still though, above might be the only way one could on Windows.
