Native application (Mac, Win) with access to local system files?

Question

macOS

It is necessary to build a cross-platform application (Mac, Windows) based on one of the solutions:
- nwjs.io
- https://github.com/appjs/appjs/wiki/HTML5:-Read-lo...
- https://github. com/kjellberg/nightrain
Scenario:
- launch the application
- drop an image from the desktop into the application - the
image is displayed in the application
- if the file with the image is updated, then you need to update the image in the application
Problem:
All available frameworks specified by yours cannot get full access to file system to update the file itself or check the file update date.
Question:
- What is the shortest path to get the full path to the file so that it can be updated from the application. At the same time, is it important that web technologies be used to create an application?
