How disable icon previews in Open File dialog, and show native document icon?

Greg Willits wrote:

The macOS Open File... dialog shows a list of files. Thes files are displayed as previews instead of with the native document icon. In Finder my display preferences are to show document icons. I want these same icons in the Open File dialog. I cannot find any setting for this. All attempts to search comes up with only articles about to use cmd-J in Finder (which is not the answer — as seen in my image).

The image shows the exact same folder viewed in Finder with icons overlaying an OpenFile dialog (Numbers in this case) with previews. Clearly the Open File list does not follow the same settings as Finder.

Anyone ever dig into this? Found a command line prefs setting to change maybe?

Thanks.

Command i opens the information pane— verify you have the default application set to your preferred app...(?)

Yep — Info panel shows the correct default application.

And, just for clarification — This preview of files happens with applications whether an Apple app (Numbers, Pages, Safari) or not (Nova, Graffle, Photoshop, others). All file types assigned their default apps, in folders known to not have "Show Icon Previews" checked.

One app showing some difference is BBedit. It's not showing .txt files as previews in the open dialog (even if I enable them in Finder for the folder), but it does show other files (images, .css, .html) files as previews. So that exception could be the application's own hard-coded choice. (It's not the OS ignoring previews, since Finder makes previews for .txt.)

I guess this is a default OS thing (I have two computers behaving the same). I just know it wasn't always this way, and while it's bugged me for a while, I don't remember when it changed.
