Can you tell me where the 'special' drawer icons hide (ie the drawer icons for prefs, system, tools, utilities etc) and also I have found (in aros x86, wanderer) that icons are named def-icons or end with .info. Are there others?
Wander works like Amiga OS3, if a file does not have its own real icon, the operating system will assign a default one.
System default icons called def_name type.info can be found in AROS:Prefs\Env-Archive\SYS.
The recognition of the file type and the association of the icon to a file "without icon" is defined by the Datatype/Descriptors.
It is possible to create/add new Def icons to the system, but in this case it would be necessary to new install Datatype/Descriptors as well.
On my AROS One for example, for each image, a specific icon is assigned, by default Wander assigns an identical icon for all image, but also for sounds, archives et....
