How to force folder refresh in Sublime, when “Project > refresh” doesn’t work?

1. Open Sublime Text.
2. Select Preferences from the top menu and click Key Bindings – User. Here you will see a JSON file that should contain an array of objects (initially the array is empty). Every object will represent a shortcut.

3. Add the following (new shortcut object) entry into the array (between the brackets):

   { 
       "keys"    : ["f5"], 
       "command" : "refresh_folder_list" 
   }
   

You should be able to refresh the folders with F5.
