if I put "Show hidden files and folders" in the search bar (taskbar) it takes me directly to the settings which shows hidden files should be visible.

I see up to: c:\Users\{your username}\AppData\Roaming\Microsoft\
in there is a few folders but not building blocks or 1033

You mention i could save in a different template? I only see 2 options to save either building blocks or Normal. Can I add a new template, but still, would I be able to see it if I can't see the default files?
