Amiga Workbench icon

Amiga Workbench icon is a family of unnecessarily-complicated icon formats used on Amiga computers.

This article describes the original format (sometimes called "Old Style icon", or something to that effect). For information specific to the newer formats, refer to NewIcons and GlowIcons.

An icon file is typically located alongside the file to which it is associated. For example, a file named  would be associated with the file named.

Some files contain a second image, to be displayed when the icon is selected.

Icons in the original format can have up to 4 colors. The actual colors displayed depend on the user's Workbench palette.

Identification
Files begin with bytes. But make sure the file is not actually in NewIcons or GlowIcons format, which have the same signature.
