Hi Anson-

I apologize your student lost their files. You should never place additional files inside the OO file package. When the file is saved in OmniOutliner, it creates a separate file that is the new version and overwrites the old one. This is how OS X handles file packges. Since the addition files inserted aren't known to OmniOutliner, it doesn't copy them over.

The best suggestion I can give you is to try a data recovery program to search for lost and deleted files.

If I can be of anymore help, please let me know.
