Backup and restore

This may not belong in this forum, but I'm having trouble with the Import feature.

What happens is that I imported a test from another course (I use the import feature to deploy my tests throughout the courses on the Moodle site) but say I have a folder for "French_1501" and beneith it I have "Test_2" and "Test_3". When I import the test into the new courses that only have "French_1501" -> "Test_2" the "Test_3" folder does not get copied into the "French_1501" folder. In order for the images to display properly, I have to manually upload the .zip and unzip into each course.

Basically, is there a workaround for this? Is it a bug or "feature"?

I know I could delete the existing folder and it will copy over the entire contents again, and I know I can upload the .zip for each course, but is there a reason why it will not update files in an existing folder?

Thanks
