@ducky710 Files UWP doesn't support hidden folders yet.

Also there are permission issues on AppData (if you type the path you'll get AccessDenied).
For this particular case, typing "C:\Users\USER\AppData\Local" works while "%LocalAppData%" won't.

That's because of environment variables weren't supported before, it works now.

@soumyamahunt It's not a duplicate since this a bug report and that's a feature request.

Merging with #2303.
