Since some months I have the really nasty problems that files are always
shown as symbols, but I want the detail view. Even when I select detail
view, next time I open the dialog that setting is ignored.
I found this thread via a web search. Looks useful, although there's a lot to digest.
File Explorer has a fairly complex system of overrides for deciding how folders are displayed in it, made even more difficult by all the details being hidden in the registry without any UI.
