Default System Icon Files are Not the Same as Displayed

I noticed something really odd. I wanted to use the default folder icon on my Mac running Big Sur, and edit it to add some custom flair to my icons. I followed the path:

System/Library/CoreServices/CoreTypes.bundle/Contents/Resources

and found my system assets no problem. But when I found the file GenericFolderIcon.icns, that's when I realized something was up.


Here is the image that file contains:



And here is what folders actually look like on my machine (taken from the get info window):



That's a really clear difference! So where is the real location of my system icon assets, and why does my machine have outdated versions of icons being retained?

I suppose it’s possible, but if you look closely, the folders are a different shape. It wouldn’t make much sense for them to be dynamically changed that much before displaying them.

It also doesn't make much sense to load a folder full of files that are not used.

I suppose they could be there to support older, less capable hardware.

Maybe they dynamically draw the folder icons and those are used for the images only.

Maybe Apple is just messing with the people who want to change the icons and have left them there as a red herring.


Finder has an Assets.car file, but I don't know how to open it to see if there are icons in it.
