Can't see the .aup or other project files in Windows Explorer

Just downloaded 3.2.3 and created a project. But the .aup and other project files do not show up in the Windows File Explorer. I turned on the viewing of hidden files, but still I do not see them. What gives?

So beginning in Audacity 3.0, Audacity projects are now contained within a single “.aup3” file. The old .aup and it’s associated directories and sub-directories are no longer used.
