Very interesting. According to the documentation if I want to store the reference and want it to persist after a reboot I need to do a bookmark.
You should not store or archive file reference URLs. A file’s ID may be different for different boots of the operating system. If you need to store a URL, see “Working with Bookmarks and Aliases.” THANK YOU so much for pointing me in the correct direction.
