Is it possible to make the icon of a specific file-type have an icon based on its contents.

Like for example images on OS X, which shows their thumbnails.

  • But is that a just a quicklook plugin, or does it also change the icon in Finder? – Tyilo Jan 31 '12 at 00:30
  • the QuickLook preview will be used in some cases. Try browsing your text files "as Icons" in Finder. – justin Jan 31 '12 at 00:38

    A QuickLook plug-in can generate two different things: “previews” and ”thumbnails”. Thumbnails are used as icons. – Jens Ayton Jan 31 '12 at 07:03
