Answer 1

Using Automator I could build a Folder Action workflow to display the path of a file moved to a folder using only JavaScript:

function run(input, parameters) {
   var app = Application.currentApplication();
   app.includeStandardAdditions = true;
   var text = "FileName = " + input[0];
   var options = { };
   app.displayAlert(text, options);

   return input;
}

I hope that could help.
