Change default icon for zip files in thumbnail view

How do I get the thumbnail view to show my own icon? I want to show the 7zip icon on zipped files instead of directory opus default. It works in details view but not thumbnail.

Went to file types and changed it there as well but does not work

They're thumbnails, not icons. They'll include images inside the zip if there are any (and it's not turned off in Preferences).

You can turn them off via Preferences / File Display Modes / Thumbnails / Folders / Display thumbnails for folders, but this also turns them off for normal directories/folders as well.

Yeah I noticed that. Is there a way to treat zipped folders differently? Cause on windows explorer I can just make zipped folders the 7zip icon instead of containing images like normal folders.

Is there a reason why the checkbox " Use Windows folder thumbnails where possible" doesnt work for zipped files and only the folders?

Looks very weird here with the contrasting styles

Okay I kind of got it by unchecking include images as folder contents only for directory opus thumbnails
