Seems to me that file contents is likely to change far more often than filepath. And applications that edit contents tend to retain the same name for the edited file.
Plus, even if you copied a file verbatim to a different path, they are no longer the same file as they are likely to be parts of different applications and/or websites. As such, the contents are likely to diverge over time as the separate apps/sites change.
In short, I'd use the filepath.
