As the question suggests, is the Default directory hidden on windows ? View Package File is able to open any files in Default but when I try window.open_file(sublime.packages_path() + "\\Default\\exec.py") it just opens an empty view with the following message in the console.
Unable to open /C/Users/user/AppData/Roaming/Sublime Text 3/Packages/Default/exec.py
Why is that ?
