Missing Reports Inbox/Favorites

First off, I apologize if I've posted this in the wrong forum. Please move it to a more appropriate forum if needed.

I have a user that for some unknown reason has lost the reports contained in his Inbox and Favorites. Two questions;

1.) Are reports in an Inbox and/or Favorites just links to reports stored elsewhere in the repository?

2.) Which table\s might I be able to look in to locate the reports?

I'm thinking that for some reason they have just been abandoned in the repository and the link to the owner may be corrupt? If anyone has any other suggestions as to what I might be able to try, please feel free to share them.
