Notify user when a file has been updated / changed in the resources folder

Hi doe's anyone know if it is possible to track and alert users if a file updates in the project resources.

My hype file will be embedded within an LMS and use json to load content in so I would like to create a banner to notify users if a piece of learning updates.

Users will see the banner and reload the 'app' to refresh the content.

Thanks in advance!
Stephen.
