    1. COWhen you say "not created in the application" - what *did* create the file? If it's not created by your application, why would you expect it to be in the user store for the application?

    3. COI suspect it's not in isolated storage then - at least not in the user part of isolated storage. If it's in the project, you may be able to access it as a resource URL, or just embed it in the assembly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
