Not safe to persist NSURL using absoluteString() for file URLs

[BennettSmith]

When persisting an NSURL to the database it is not safe to simply convert it to an absolute string and store it. If the NSURL is storing a file URL then the resulting string will not work to reconstruct a valid file URL. Instead, it should persist to disk as a bookmark in a BLOB. Since the field type would differ based on whether the NSURL is a file URL or not I am unsure how to fix this.

Are you saving the entire path or just the file path within the app directory?

The latter is how I'm doing it with no prob.
