GlowIcons (or Glow Icon) is the native icon file format for AmigaOS 3.5–4.0. It is sometimes known as OS35 images or OS3.5 extension icons.

Format
A GlowIcons file is (more or less) a valid original format icon file. It contains an icon (or pair of icons) in the old format, which will be displayed by applications that don't support GlowIcons format. Sometimes this icon is just a placeholder (a blank 1×1 or 4×4 image is common), and sometimes it is a low-quality version of the real icon.
Starting at the position where a file in the original format would be expected to end, the real GlowIcons data begins. Locating this position in the file is nontrivial.
The GlowIcons data is in IFF format, and so begins with the ASCII string "FORM".
Identification
As with all the major Amiga icon formats, files begin with bytes 0xE3 0x10.
The ASCII string "FORM" appears somewhere in the files, followed (with 4 intervening bytes) by "ICON".
