The icons on the root directory of the QFG Collection are multiple image icons.  
They contain both the 16 color and 256 color icons in a single icon file.

When Windows 95 is in 256 color mode, it will display the 16 color icons.

When Windows 95 is in high color or true color mode and you have Microsoft Plus!
set to use all icon colors, you'll automatically see the 256 color icons.

I separated the 16 color and 256 color icons for those of you who do not 
use Microsoft Plus!.  You can change the properties of the QFG icons in the
Sierra group to use any of these icons.

The "ALT" icons were ones I made by hand for the original QFG Anthology.  
You can see I've learned a lot since then!

Enjoy!
