I posted about these a long time ago, but haven't gotten around to uploading them until now:
Pathfinder: Folder Icons for Mac and PC
Chaosium Basic Roleplaying: Folder Icons for Mac and PC
Labyrinth Lord: Folder Icon for Mac
Swords & Wizardry: Folder Icon for Mac
Because of technical hurdles, the Mac icons are generally enlargeable to 128x128 pixels, whereas the Pathfinder Windows XP icons can only be enlarged to 48x48.
