Dear Mr. Muhammed Yamin,
As I understood from your question you have a problem with your local file to see it from outside the network, I think if you want to use these files from another network you have two solutions:
1- If you have shared server between your company you can but your file in this server and easily access it from any network connected to the server.
2- you can upload your file to any cloud storage such as (Dropbox, Google Drive, Etc…) and you can hyperlink your file with the file location.
I hope this was useful for you.
Regards,
